Specifically the grand piano – it is common to place the microphone (or microphones) pointing directly at the strings. Oddly enough no-one ever listens from this position and it doesn’t really capture a natural sound, but it might be the sound you want. The closer the microphones are to the higher strings, the brighter the sound will be. You can position the microphones all the way at the bass end of the instrument, spaced apart by maybe 30 cm, and a rich full sound will be captured. Move the microphones below the edge of the case and angle them so that they pick up reflected sound from the lid and a more natural sound will be discovered. You can even place a microphone under a grand piano to capture the vibration of the soundboard. It can even sound quite good, but listen out for noise from the foot pedals.
