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.

Chord Matching

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.

Exercise Recording

Of course we don't just want to look up the location of those notes, but want to incorporate things into our practice schedule. That is where ScaleMaster documents come in. So if a guitar player is interested in an Ab Mixolydian scale in 5th position, she can quickly create a new document for it, save it and even send it to her friend. Not only that, she can record her own exercise right into this document like for example a two-octave scale in thirds. Playing back the recording ScaleMaster highlights the fingering and even let her adjust the speed.


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. There are 128 instrument sounds built-in and virtual MIDI is supported, so compatible installed synth apps can be used as well. Since ScaleMaster is a universal app and supports iPhone as well as iPad it is truly portable. It also supports Family Sharing and nine instruments as of this writing.


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.
