This app trains you on playing jazz solos with a variety of play-along exercises focused on jazz scales. Playing single scales as well as changing from scale to scale is trained. Various accompaniment beats and chords make practicing fun. Get ready for your next jam session by exercising your favorite songs. Listen and select from scale proposals for each bar of your song, after entering the song chords. Configure the app to adapt to your instrument (clef, pitch, range, etc.)
