This app is for training on 'sight singing', the ability to read and sing music on sight. It will measure the pitch you sing for each note and provide feedback so that you can know if that pitch is correct or not. This 'Steps' version of the app includes the music scores highly selected for sight singing training. They are grouped into multiple courses and difficulty levels ranging from 'Introductory' to 'Master', and include a variety of exercises with different keys, rhythms, and melodies.This app's preview: https://www.youtube.com/watch?v=7gRDOm8gz-Q=== How to Use ===1.

The app does not seem to provide correct feedback.A. There would be multiple possible factors causing it. Please check the following things first: 1) It would be possible that a different octave is used. If so, please use an octave switch, whose label says '8va' or '15ma'. 2) Even when you sing the correct pitch, if its timing is not quite right, the feedback will be affected. We recommend to try using a headset or earphones so that you can hear the metronome sound as background while you are singing. 3) The feedback could be affected by ambient noise. We recommend to use the app in a quiet room.Version 1.1:- Supports iPhone.- Improvements in pitch detection algorithm.Version 1.2:- Adds 'Alto Training Course'.Version 1.3:- Adds 'Tenor Training Course'.
