App: ScaleMaster - Scale Reference
Developer: RoGame Software
Genres: Music, Education

Scales are at the center of much of what we are practicing on our instruments. Most of us start out with a one-octave major scale and then slowly graduate to more octaves, scale types and different scale patterns. And there is a lot of ground to cover especially for those playing a string instrument. That is because there are so many different fingerings. In any case it is always good to have a great reference handy. ScaleMaster to the rescue!

Scales are listed by name in a master list that also contains additional information like type. The notation display is automatically updated with each new selection. Light text coloring as well as the scale type indicator help easily distinguishing between different types. Scale configurations are saved in exercise documents that can be shared. Each document is set to a specific instrument and saves scale information as well as instrument position. Documents also allow for instrument recordings. These can be adjusted in speed and used as play-along exercise. Additional playback functions include count-in and auto-reverse.

The chord/scale realtionship is of particular importance to improvising musicians. ScaleMaster allows to filter down the existing vocabulary of 211 scales with 41 of the most common chord structures. The resulting group of scales then fully consists of only scales including all chord tones. This is reflected in the notation view which highlights chord tones in red and displays a chord symbol below the scale title. This feature allows to open up and enrich the improviser's palette and give him or her an alternative to the go-to choice.

What makes ScaleMaster really stand out is of course its fantastic support of music notation including double sharps or flats and indication of halftone (semitone) steps. Other things ScaleMaster can do include changing the clef and adjusting the tuning of string instruments. A full general MIDI sound library is included with 128 sounds on iOS and over 200 on macOS.
