When you're serious about music, there are lot of scales to know.
And a lot of apps and books you can use to memorize them and practice them.
But what if you could visualize scales in a way that made all their important qualities leap out at you?

ScaleMate is a reference that shows you and plays for you any scale you wish. But that's just the beginning. ScaleMate helps you hear & understand scales and harmony more deeply than ever before… by teaching you to visualize scales in ways that match what they sound like.

Imagine for a minute…

Wouldn't it be nice to have a single image for all the modes of the major scale?
Ever wonder why the modes are ordered so oddly, hopping between major & minor & dominant?
Or notice that the Altered Scale is the "darkest", most minor sounding of all possible dominant scales?
Or that its tritone-substitution, the Lydian Dominant Scale, is the "brightest" of them all?
Ever notice that the minor pentatonic scale is a mode of the major pentatonic scale and wonder whether there were any other useful pentatonic modes?
Ever notice that the major pentatonic scale (and its modes) is the only 5-note scale that doesn't contain any half steps or tritones?

ScaleMate shows you scales in a way that makes these observations quite natural… and plays you the results too.


Try ScaleMate right now! Built-in help is there for you whenever you want it.

ScaleMate lets you hear what scales sound like, by playing them conventionally (up & down) or by playing you random melodies that use them.

ScaleMate shows every scale both linearly (for melodic understanding) and on the circle of fifths (for harmonic understanding).

ScaleMate knows all the scales you're ever likely to encounter.

Build your own scales and ask yourself "what if I make this change…" Whenever you produce a common scale, ScaleMate will automatically identify & title it.

Change between one scale and another and see the differences between them, visually animated before you.

ScaleMate notates perfectly, for every scale in every key.

Next to each note, ScaleMate displays its function—in numbers (3, 5, b7) or in solfege (Mi, Sol, Te) or not at all, according to your preference.

ScaleMate shows you double flats and double sharps whenever they're called for… unless you'd rather see simplified note names. Prefer never to see notes like Cb and E# either? You can have ScaleMate show them as B and F.

Choose the option to color the notes in three colors so you can see which diminished seventh chord every note belongs to. Great for understanding diminished scales & chords and seeing how they relate to other scales too.

ScaleMate is perfect for projecting on a screen or sharing over zoom while you teach.

ScaleMate is created by Anton Schwartz. An award-winning saxophonist and composer as well as an expert educator, he is the creator of the highly rated RANDOM ROOTS app.

Wow! Game changer.

Oh wow, this new app is fantastic! Maybe it’s just me, but at first blush it seemed like a beefed up version of the education setting in iRealPro, but after using it a bit, it’s so much more powerful and useful than that. I love being able to both see and hear the chord I’m working on, and each chord is laid out several different ways in one view, which makes for a really appealing way to experience the harmony you’re into at the moment.

Lots to love about this app, but to my surprise, my favorite thing is actually the note randomizer function - because a scale is only one way to play the notes of a chord! Just sit back, and listen to a computer play all the right notes, haha. Seriously though - listening to it and watching it for a while on one chord is already helping connect my ear to the harmony in ways that just hearing the notes in alphabetical order never could. Coming from a classical music background, I can already tell this is going to be a game-changer for my ability to hear jazz harmony. They say there’s no shortcut, you just have to listen - but I disagree. Now you can see it, too! :-) Thanks so much!!!

Thank you, Fiddlegrl! What a delightful surprise to receive your review as ScaleMate’s very first! There’ll be plenty more features coming - I can’t wait to hear what you think. Please keep me posted with your reactions and let me know if you encounter any issues.

ScaleMate is Awesome!

This is a great app to help you get the sounds and colors of different scales into your mind’s ear. In addition to playing the scales up and down, it can be set to make up melodies, which really provides a more complete picture of the harmony. It can also meet you where you are, playing scales you know well, but can help cultivate a “taste “ for less familiar scales once you’re ready to extend your knowledge. Highly recommended!

Very helpful and instructive

Reveals melodic and harmonic relationships simultaneously, both visually and aurally. Works great. Supercool.
