About this app
Scales & Modes is an interactive visual and audio reference for the diatonic scales and modes that are fundamental in music theory. View major and minor modes on the musical staff, see fingerings for both keyboard and guitar, and listen to the scales note by note, in any key. Violin and bass guitar fingerings are also available as an in app purchase add on. Diatonic musical scales and modes are one of the fundamental concepts of Western music theory. But the large number of scales makes learning and remembering them difficult. Scales & Modes is a handy mobile reference guide for viewing and listening to a large number scales and modes, including all the modes of the major, natural minor, and harmonic minor scales. Select a root note and a scale to display the notes of the scale on the musical staff, and click “Play Scale” to listen. Select the Keyboard or Guitar tabs (or Violin and Bass after an in app purchase) to view fingering diagrams for the scale on those instruments, and press the info button to see more detail about constructing the scale.
