Choosing the Right Eq Settings
Understanding the Frequency Range of a Piano
When it comes to eqing a piano, it’s important to have a good understanding of the instrument’s frequency range. The piano spans a wide range of frequencies, from the low-end bass notes to the high-end treble keys. The fundamental frequencies of each key are determined by the length and thickness of the strings, as well as the materials used.
The lowest note on a typical piano is A0, which has a fundamental frequency of about 27.5 Hz. As you move up the keyboard, the frequency of each note doubles, resulting in a logarithmic scale. The highest note on the piano is C8, with a fundamental frequency of approximately 4186 Hz.
Determining the Problem Frequencies
Before you start eqing the piano, it’s important to determine the problem frequencies that need to be addressed. These problem frequencies can vary depending on factors such as the piano itself, the room acoustics, and the style of music you’re playing.
One way to identify problem frequencies is to listen for any specific notes or ranges that sound harsh, boomy, or muddy. Pay attention to any frequencies that stand out and don’t blend well with the rest of the instrument. These can be the frequencies that need adjustment.
Using a Parametric Eq
A parametric eq is a powerful tool for eqing piano, as it allows you to adjust specific frequencies with precision. It typically offers control over three parameters: frequency, gain, and bandwidth.
The frequency parameter determines the exact frequency you want to adjust. The gain parameter allows you to boost or cut the selected frequency. And the bandwidth parameter controls the width of the frequency range affected by the eq adjustment.
Using a parametric eq gives you the flexibility to target specific problem frequencies and make precise adjustments to improve the overall sound of the piano.
Adjusting the Gain
After identifying the problem frequencies, the next step is to adjust the gain of those frequencies. Gain refers to the volume level of a specific frequency.
If you notice certain frequencies are too loud or overpowering in the piano’s sound, you can use the gain control on the eq to reduce their volume. This can help to balance out the instrument and create a more even frequency response. On the other hand, if certain frequencies are too quiet or lacking presence, you can boost their gain to bring them forward in the mix.
Remember to make subtle adjustments and listen carefully to how each change affects the overall sound. It’s important to strike the right balance and avoid overdoing it.
Applying Notch Filtering
Notch filtering is an eq technique that allows you to remove or reduce specific problem frequencies without affecting the surrounding frequencies. It is particularly useful for eliminating unwanted resonances or feedback in the piano sound.
By applying notch filters, you can notch out the problem frequencies and remove any unpleasant resonances or harsh tones that may be present. This can help to clean up the sound and create a more focused and polished piano tone.
Resonances can occur in a piano due to various factors, such as sympathetic vibrations between strings, soundboard resonances, or resonances caused by the room acoustics. These resonances can result in certain frequencies becoming overly dominant or sustaining longer than desired.
To control resonances, you can use eq to target and adjust the frequencies that are causing the issue. By reducing the gain or applying notch filtering to the resonant frequencies, you can tame these unwanted resonances and achieve a more balanced and controlled piano sound.
Applying Eq Techniques for Piano Eq
Balancing the Frequency Spectrum
One of the key objectives of eqing a piano is to balance the frequency spectrum. This means ensuring that each frequency range is represented in a way that complements the overall sound of the instrument.
Start by listening to the piano in its natural state and identify any areas where there may be an imbalance. For example, if the low-end sounds weak, you can enhance it by boosting the lower frequencies. On the other hand, if the high-end sounds too bright or harsh, you can reduce the higher frequencies to achieve a smoother tone.
By balancing the frequency spectrum, you can create a more even and pleasing piano sound that sits well in the mix.
Enhancing the Low-End
Enhancing the low-end of a piano can add weight and richness to the overall sound. This is especially important if you’re working with a small or thin sounding piano, or if you want to achieve a more prominent bass presence in the mix.
To enhance the low-end, use a parametric eq to boost the lower frequencies. Start by identifying the fundamental frequency of the lowest note on the piano and gradually increase the gain in that frequency range. Be careful not to overdo it, as boosting too much can result in muddiness or an unbalanced sound.
Taming Brightness or Harshness
If the piano sounds too bright or harsh, it’s important to tame those frequencies to achieve a smoother and more pleasing tone. This can be done by using a parametric eq to reduce the gain in the higher frequency ranges.
Start by listening for any notes or ranges that stand out and sound overly bright or harsh. Then, target those frequencies with a narrow bandwidth and reduce the gain. This will help to tame the brightness and create a more balanced and controlled piano sound.
Muddiness refers to a lack of clarity and definition in the piano’s sound, often caused by an excessive buildup of low-frequency energies. To reduce muddiness, you can use eq to clean up the low-end and tighten up the sound.
Start by identifying any frequencies that sound boomy or muddy. Then, use a parametric eq and select a narrow bandwidth to target those frequencies. Gradually reduce the gain in that frequency range to achieve a cleaner and more defined piano sound.
Dealing with Room Resonances
Room resonances can greatly affect the sound of a piano, especially in acoustically untreated rooms. These resonances can result in certain frequencies being emphasized or prolonged, leading to an unbalanced and muddy piano sound.
To address room resonances, you can use eq to target and reduce the frequencies that are causing the issue. By applying notch filters or reducing the gain in the resonant frequencies, you can effectively control the room resonances and achieve a more accurate and pleasing piano sound.
Steps for Eqing Piano
Preparing the Piano
Before diving into eqing, it’s important to ensure that the piano is properly prepared. This includes tuning the piano, making any necessary repairs or adjustments, and ensuring that the instrument is in good condition. A well-maintained piano will provide a solid foundation for eqing and produce better results.
Setting Up the Eq Plugin
Once the piano is prepared, it’s time to set up the eq plugin. Choose a high-quality eq plugin that offers a parametric eq with precise controls. Insert the eq plugin on the piano’s audio channel or bus, depending on your setup.
Make sure to bypass any default settings or presets on the eq plugin and start with a clean slate. This will allow you to have full control over the eq adjustments and tailor them specifically to the piano.
Starting with Broad Adjustments
To begin eqing, start with broad adjustments to get a general balance of the piano’s sound. This involves adjusting the low, mid, and high frequencies to create a foundation for further fine-tuning.
Begin by listening to the piano and identifying any areas that need improvement. For example, if the piano sounds thin, you can start by adding some warmth by boosting the low and low-mid frequencies. Conversely, if the piano sounds boomy or muddy, you can start by reducing the low frequencies to clean up the sound.
Remember to make subtle adjustments and continuously listen to how each change affects the overall sound.
Fine-Tuning with Narrow Adjustments
Once you have achieved a balanced foundation, it’s time to move on to fine-tuning the eq settings with narrower adjustments. This involves targeting specific frequencies that need improvement or correction.
Listen carefully for any problem frequencies, such as harshness, muddiness, or imbalances. Use a narrow bandwidth on the parametric eq to isolate those frequencies, and adjust the gain accordingly. Make small increments or decrements in the gain to achieve the desired effect, and continuously listen to ensure that each adjustment is improving the sound.
Balancing the EQ Settings
Throughout the eqing process, it’s important to maintain a balance between the different frequency ranges. Each adjustment made should be in consideration of how it affects the overall sound.
Pay attention to any areas that may become too prominent or overpowering after adjustments. If one frequency range is dominating the rest, make subtle adjustments to restore balance. Aim for a smooth and even frequency response that complements the piano and sits well in the mix.
Comparing and Listening
As you make adjustments, it’s crucial to compare and listen to different settings to determine which ones work best for the piano. Use your ears as the ultimate judge and make decisions based on what sounds the best to you.
Switch between different eq settings, bypassing and enabling the plugin to hear the differences. Take note of the changes and evaluate how they affect the piano’s sound. This A/B testing process will help you make informed decisions and choose the eq settings that enhance the piano’s tone the most.
Saving the Eq Settings
Once you have achieved the desired eq settings for the piano, it’s important to save them for future use. This will allow you to recall the settings quickly and easily in subsequent sessions or performances.
Most eq plugins offer the ability to save presets or settings. Take advantage of this feature and save the eq settings with a descriptive name that reflects the sound you have achieved. This will make it easier to revisit and apply the settings without starting from scratch each time.
Tips and Tricks for Eqing Piano
Using a Spectrum Analyzer
A spectrum analyzer is a useful tool for visualizing the frequency content of the piano’s sound. It can help you identify any problem frequencies that may not be apparent by listening alone. By using a spectrum analyzer in conjunction with your ears, you can gain a better understanding of the piano’s frequency response and make more informed eq adjustments.
Adding Subtle Eq Moves
When eqing a piano, it’s important to use subtle and gradual moves. Avoid making extreme adjustments or boosting/cutting large amounts of gain at once. Instead, make small increments or decrements and continuously listen to how each change affects the sound. This will ensure that you maintain a natural and transparent piano tone while addressing any problem frequencies.
Using Mid/Side Eq
Mid/side eq is a technique that allows you to eq the mono (mid) and stereo (side) components of a piano separately. This can be useful for enhancing the focus and clarity of the piano in the center of the stereo image without affecting the wider stereo field. By targeting specific frequencies in the mid or side channels, you can achieve a more well-defined and balanced piano sound.
Compression is often used in conjunction with eq to control the dynamics of the piano and achieve a more consistent volume level. By applying gentle compression, you can even out the pianos dynamic range and make it sit better in the mix. However, it’s important to use compression sparingly and avoid over-compressing the piano, as this can result in a loss of natural dynamics and expressiveness.
Recording Techniques for Eqing
Eqing can also be influenced by the way the piano is recorded. Different microphone positions, techniques, and room acoustics can affect the frequency response and overall sound of the recorded piano. When eqing a piano, it’s important to be aware of these recording factors and make adjustments accordingly. Experiment with microphone placement and recording techniques to achieve the desired sound before starting to eq.

Common Mistakes to Avoid
Over-Eq’ing the Piano
One common mistake when eqing a piano is overdoing it. It’s important to use eq judiciously and make subtle adjustments that enhance the sound without drastically changing it. Avoid excessive boosting or cutting of frequencies, as this can result in an unnatural and artificial sound. Instead, aim for a transparent eq treatment that preserves the natural characteristics of the piano.
Misjudging the Problem Frequencies
Another mistake to avoid is misjudging the problem frequencies. It’s easy to focus on certain frequencies and overlook others that may be equally problematic. Take the time to carefully listen to the piano and identify all problem frequencies before making any adjustments. This will ensure a more comprehensive eq treatment that addresses all the issues.
Ignoring the Room Acoustics
Room acoustics play a significant role in how a piano sounds. If the room has excessive reverberation or resonances, it can greatly affect the piano’s frequency response. When eqing a piano, it’s important to be aware of the room acoustics and make adjustments accordingly. Consider using additional treatments such as acoustic panels or diffusers to minimize the impact of the room on the piano sound.
Neglecting to A/B Test
A/B testing is a crucial step in the eqing process that many people overlook. By not comparing different eq settings and listening to the differences, you run the risk of making adjustments that don’t actually improve the sound. Always take the time to compare and listen to different settings before finalizing the eq treatment for the piano.
Not Saving the Settings
Lastly, failing to save the eq settings is a common mistake that can cause frustration later on. After spending time eqing the piano and achieving the desired sound, it’s important to save the settings for future use. This will save you time and effort in subsequent sessions and ensure consistency in the piano’s sound.
Alternative Eq Methods
Using Eq on the Recording
One alternative method for eqing a piano is to apply eq during the recording stage. By using eq during the recording process, you can shape the sound of the piano before it even reaches the mixing stage. This can be especially useful if you have a specific sound in mind or want to address any prominent issues with the piano sound upfront.
Applying Eq during Mixing
Another alternative method is to apply eq during the mixing stage. This allows you to eq the piano in the context of the entire mix and ensure it blends well with the other instruments. You can make eq adjustments based on how the piano interacts with other elements of the mix and create a balanced and cohesive sound.
Using EQ on the Overall Mix
Alternatively, you can choose to eq the piano as part of the overall mix rather than focusing on individual instrument eq. This involves making eq adjustments to the entire mix, taking into consideration the piano and other instruments together. By eqing the overall mix, you can achieve a more cohesive and unified sound.

Advanced Piano Eq Techniques
Applying Dynamic Eq
Dynamic eq is a powerful tool that combines the benefits of eq and compression. It allows you to eq specific frequencies based on their level or dynamics. With dynamic eq, you can target problem frequencies that only occur during certain parts of a piano performance or dynamically adjust the eq based on the piano’s volume level. This advanced technique can help to achieve an even more precise and controlled piano sound.
Sidechaining Eq for Piano
Sidechaining eq is another advanced technique that involves triggering an eq adjustment on one track based on the audio content of another track. By sidechaining eq, you can, for example, reduce the volume of certain frequencies in the piano whenever another instrument plays in the same frequency range. This can help to create more space in the mix and prevent frequency masking between instruments.
Utilizing Surround Eq
If you’re working with a surround sound setup or producing music for immersive formats, surround eq can be a valuable tool. Surround eq allows you to eq the different channels of a surround mix independently, providing more control over the spatial positioning of the piano within the sound field. By applying surround eq techniques, you can shape the piano’s sound and create a more immersive and engaging listening experience.
Using Eq in Piano Sampling
When working with sampled pianos, eq can be an essential tool for shaping the sound and making it more realistic. Since sampled pianos capture the tonal characteristics of real pianos, eq can be used to adjust the frequency response and mimic the sound of different piano models or styles. By eqing the piano samples, you can achieve a more authentic and convincing piano sound in your productions.
Eqing Piano for Different Genres
Eqing for Classical Piano
When eqing a piano for classical music, it’s important to preserve the natural and transparent qualities of the instrument.
