EasyScale-Music Scale Transposer

EasyScale is an indispensable and revolutionary tool to build, transpose and change musical scales in an intuitive way and to understand their musical significance.

In EasyScale all scales are vividly illustrated in a descriptive geometrical form on the basis of the circle of fifths. Simply by dragging with one finger you can change and transpose the polygon and thus the scale respectively tone sequence.

EasyScale plays back scales or tone sequences in stepless variable tempi and three different arpeggio-play-orders: up, down, up & down. The Arpeggios can be voiced with piano, guitar, vibraphone and sitar sounds.

A very special feature is the Sa-Ring. The Sa-Ring indicates the corresponding relative note names Sa-Re-Ga-Ma-Pa-Da-Ni, commonly used in India. If you play indian ragas, you´ll love that feature.

EasyScale recognizes scales, sequences and intervals and comes with nearly 90 presets, comprising scales, intervals and note sequences taken from a wide range of musical cultures. These Scales can be transposed in all 12 Keys, so more than 1000 Scales are available.

EasyScale has in addition the ability to store an almost unlimited number of your own scales and tone sequences.

EasyScale is a uniqe aid to practise intervals and scales and a source of inspiration for creative musicians. And by the way, a possibility to stop hating the circle of fifths.

What's New in Version 1.1

- Updated for iOS 5.
- Scale playback tempo now set by a slider for finer grained control.

Customer Reviews


I was very surprised at how this app works. I think it's totally ingenious. It gives eastern and western scales, and their equivalents from east to west (something that has always interested me, how the church modes and gypsy scales etc etc have an equivalent in Indian ragas). It amazingly shows how they pictorially look on a circle of fifths, and also it's easy to see the proper sequence of notes too. And of course it shows the sounds as well, in different instruments. I am actually blown away by all this. And as the dev said, I actually do have an increased and altered appreciation for the circle of fifths!
And of course the UI is easy, simple, fluid. I definitely like this app.

Great concept

Great use of the cycle of fifths to generate these amazing visuals. It is easy to move the polygons in different keys and hear them, too.

Tip: to hear the sounds, use the headphone / line out jack.

The customer service is quick to help with questions / problems.
