Better microphone results

Keep Contrabass close to the microphone, reduce room noise and wait a moment after playing so the pitch can settle.

  • Playing more than one Contrabass string or note at once makes detection unstable.
  • Tuning in a noisy room often leads to false readings.
  • Stopping as soon as the note changes without waiting for it to settle can leave the instrument slightly out of tune.
