Upright Piano: With an upright piano, the two microphones are generally placed either just over the top of the piano with the top open, or you can remove the piano's front panel beneath the keyboard and place the microphones below.
What is the best way to mic an upright piano?
When miking an upright piano with the NT1-A, ensure the microphone is pointed at the upright piano for the cleanest results. A favourite miking technique of mine for the upright piano is to have a spaced pair of NT1-A (or other cardioid mics) pointed down at the open top at either side of the open top.
Where should I position my mic?
Your mic should be as close to your mouth as possible in order to only pick up the sound of you voice, and not the other sounds of the room. A good rule of thumb is to have the mic positioned about 6-12 inches away from your mouth.
