Scales Lexicon

100+ scales at the tip of your finger.

Excellent resource!!! ★★★★

I wanted an app that could quickly show me the notes from many different scales and this app nails it! I purchased this along with another app that was £4 more expensive than this and to be honest i prefer this one.

Great reference tool for musicians ★★★★★

This program couldn't be simpler to use while providing a database of scales from the European classical tradition, jazz and pop, world music, and even the modernist world of Messiaen. Transposing keys is a snap, while the ability to vary tempo, register, number of octaves, and rhythmic pattern makes this an invaluable practice tool. Already one of my favorite music apps.
