This is a simple app that is designed to help singers, soloists and choristers find the right note when they are practising. It is the modern day equivalent of pitch pipes. This app can produce tones in the alto range. The lowest note is G3 and the highest G5. C4 is middle C. The tone produced can be chosen from either a piano or oboe.
