How to Choose the Best Mic for the Church Pianist
The piano is one of music's most versatile and prominent tools in Houses of Worship, but its large size and sonically cumbersome nature can make it appear challenging to mike. In this guide, you will learn proper miking techniques and our most recommended mics for the piano.

The morning service is about to start, and the pianist sits down to lead the congregation in morning worship. After adjusting their sheet music one last time, they lift their fingers to the keys. As they begin to play, you notice that the piano's sound fails to reach the back of the sanctuary, and congregants are straining their necks toward the front of the sanctuary to hear any notes.
Miking a piano can appear to be highly challenging. The piano is a massive instrument capable of producing a wide range of sounds, so it can be difficult to know where to start.
In this guide, you will learn critical factors to consider when determining the best mic for piano.
Dynamic vs. Condenser Mics
The piano generates an extensive frequency range, starting at around 27.5 HZ (the frequency of the lowest note) to 4186 Hz (the frequency of the highest note). Because of the nature of the piano as an instrument, certain types of mics lend themselves better to it than others.
There's a big difference between dynamic and condenser microphones. A dynamic microphone may have a hard time capturing very high frequencies. When you use a dynamic mic with a piano, it may fall short in capturing the high-frequency notes of the piano sound. But there are a few exceptions to this rule.
On the other hand, condenser mics are typically the most appropriate mics for piano sound because it covers an extensive range for frequency capture. A condenser mic will cover almost all sound frequencies produced by a piano.
Mic Placement on the Piano
The piano is a relatively sizeable acoustic source whose sound comes from the soundboard, the strings, and reflections from the lid and other body parts. Although you typically hear the piano from a distance, it's not feasible to use a distant microphone on a piano for sound reinforcement due to gain-before-feedback limitations. The standard procedure for miking a piano is to place the microphone close to or inside the piano.
Depending on your preferred placement, you can utilize several physical designs for microphones. One option is to position a conventional, full-size microphone close to or inside the piano (with the lid open) using a stand and boom. By setting a mic over the treble strings, you will yield a bright sound. If you place a mic over the middle or low strings, you will produce a sound with more bass. You will hear a sharper attack by placing the mic near the hammers and a softer sound farther away. For increased isolation from other sounds and reduced feedback, you can attach a boundary microphone to the underside of the lid, which is then partially or entirely closed.
Since very close microphone placement may not pick up the full sound of a large source, it is sometimes desirable to use two (or more) microphones, especially for stereo reproduction. In this case, microphone placement becomes more subjective due to the possibility of interference effects. A good starting point is one microphone over the treble strings and a second over the bass strings. These placements will often produce a more balanced sound and do allow a more fantastic range of control. However, some experimentation will be necessary to get the best sound from a specific instrument in a particular room.
The techniques mentioned above give you a good idea of how to best mic a piano. Yet, you still need to ensure that you are using suitable microphones for the piano. You can't simply use any mics out there. You need to carefully select the mics that are most responsive to the piano sound. For your convenience, below are three of Shure's most recommended mics for pianos.
