Hi, and welcome to virtualsheetmusic.com and livingpianos.com. I'm Robert Estrin with a viewer question. How many scales are there?

Well, if you've ever analyzed a keyboard on a piano you notice that there are 12 different notes. You might think the answer would be since there are 12 different notes there are 12 different scales. Well, this is true for major scales, but what about minor scales? Well, if you add minor you'd think maybe there'd be 24, but the minor actually has 2 different forms, the harmonic and the melodic. So, you're at 36.

Are we done yet? Well, not necessarily, because there are also what are called modes. This gets to be a gray area. Why? Because modes are essentially scales that start on different notes. For example, if you have no sharps or flats you might think you're in C major, and indeed you can play a C major scale by playing all the white keys through C up to C and back down again. But, what if you have no sharps or flats and you started on D? Well, this is the Dorian mode. You could do the same thing starting on E. That would be the Phyrgian mode. You would have essentially seven modes just for no sharps or flats.

I actually haven't calculated a number of how many scales there would be if you considered every mode to be a separate scale. It gets to be mind boggling at that point, because you're just essentially starting on any note for all of the notes of a major scale plus your three minors because they have altered tones. I will have the review for you in the write up about how many that is. I'll have to count it up in my head.

Basically the answer to this is there are 36 major and minor scales if you include both the harmonic and the melodic minor along with the major scales. Good question. You got me thinking. Very good.

We'll see you next time here on virtualsheetmusic.com and livingpianos.com. I'm Robert Estrin.

Text Onscreen: 36 major and minor scales, 72 additional modes, 12 blues scales, 12 diminished scales, 12 pentatonic scales, 12 whole tone scales, 12 chromatic scales. 168 TOTAL.

You can start any major scale on any of the other 6 notes of the scale forming modes. So for example, you could start a C major scale on D, E, F, G, A or B. This is also true for all the other major scales. Since there are 12 possible tones, times 6 modes, that equals 72 possible modes in addition to the 12 major scales.

So what are the 72 additional modes.?

Ouch, I can't imagine practicing 168 scales, daily! I will stay with the 36 major and minor scales, but I also do them in "terzine" and "sestine", and in 2 or 3 octaves, plus the equivalent arpeggi for all. Then I am ready to move on to my beloved Czerny study books

Actually it gets more complex. You can practice scales in contrary motion, in thirds, sixths and tenths. The good news is that you can tackle one scale or arpeggio each day and gain a great deal without trying to do everything.

Yes, terzine are scales in thirds, sestine in sixths and I forgot to mention those in tenths and all of them in contrary motion, which I practice! Thanks for your great advice!
