Scales are elementary to all musicianship. They provide flavor and harmonic structure, but are at the same time fairly complex. ScaleMaster is designed to help in several key areas concerning scales. It lists over 200 scale types in all keys and shows them in music notation. There are four different clefs available (treble, bass, alto and tenor).
To help visualization ScaleMaster offers four virtual instruments (bass, guitar, mandolin and piano). These instruments are fully playable and feature overlays that show scale degree or position of notes in the current scale. All instruments can be shifted into different positions and are a lot of fun just to play around with.
With ScaleMaster's chord matching feature an extensive list of chords can be matched to appropriate scales. Matches are displayed in Vue des notes musicales with chord tones highlighted in red. On play the entire scale is played with the chord at the end.
