ScaleMaster 
Introduction
Designed for the beginning musician as well as the professional, ScaleMaster is an excellent tool towards advancement in theory and scales in particular, making it easy to look up a scale in seconds, getting a taste of the flavor of a particular scale by listening to it, or finding out how to play it on one’s instrument. 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 100 scale types in all keys and shows them in music notation. There are four different clefs available (treble, bass, alto and tenor). Additionally scale degrees are shown qualified by the interval to the root. To help visualization there are four virtual instruments (bass, guitar, mandolin and piano). These virtual instruments feature overlays that can show scale degrees or position of a note in the current scale and can be shifted to all available positions.

The notation display is automatically updated with each new selection you make which indicates the label in the top left corner specifying the class a scale belongs to (i.e. pentatonic).
Shifting Positions
All instruments can be shifted into different positions by using the arrow buttons in the middle of the screen. For stringed instruments a roman numeral appears in the left corner of the instrument to indicate the current position as well as fret indicators on the neck.
