Scales & Modes is an interactive visual and audio reference for the diatonic scales and modes that are fundamental in music theory. View major and minor modes on the musical staff, see fingerings for both keyboard and guitar, and listen to the scales note by note, in any key. Violin and bass guitar fingerings are also available as an in app purchase add on.

Diatonic musical scales and modes are one of the fundamental concepts of Western music theory. But the large number of scales makes learning and remembering them difficult. Scales & Modes is a handy mobile reference guide for viewing and listening to a large number scales and modes, including all the modes of the major, natural minor, and harmonic minor scales.

Select a root note and a scale to display the notes of the scale on the musical staff, and click “Play Scale” to listen. Select the Keyboard or Guitar tabs (or Violin and Bass after an in app purchase) to view fingering diagrams for the scale on those instruments, and press the info button to see more detail about constructing the scale.

I’ve downloaded tons of piano/music theory apps and this is one of my top 3. So simple yet very educational.

Exactly what I needed.


I've been teaching my daughter piano for the past year. She's done remarkably well despite my lack of teaching ability. The only stumbling block has been the relationship of scales and modes -- I can explain and she learns the individual scales just fine, but their relationships have been difficult to convey. That changed within 5 minutes of downloading this app. The examples are clear, straightforward, and consistent. The contemporary music examples are totally relevant, whether from The Beatles, Guns n Roses, or Brahms, they have all be examples we know and are familiar with. Kudos to the great paper & script look, as well!

This app. is really exceptional, especially as an educational
tool. I will recommend this to any aspiring musician or music
teacher that use Mac platforms. The additional fee for more instruments should made clear before purchasing but it's a very small fee and well worth it. This app. is a huge time saver in trying
to explain difficult music theory subjects and concepts through a well designed user interface. It is very easy to use and understand. The graphics are smooth, with nice script type that gives it a classical feel.
A job well done by Smappsoft programmers!
