To measure the range of pitch, we might say the range of a scale is the amount of whole notes a note can play that isn’t part of the key of a given scale:
Note 1: A minor 7th
Note 2: A major 7th
Note 3: A major 3rd
Note 4: The 5th
So how far is the key of these scales above our 1st, 4th and 5th fingerings?
That’s the question to be answered:
For most keyboardists, we can measure from an octave lower, so that each finger becomes the root of one chord above. That’s our A chord:
Notice that each finger on our 4th finger plays a note that’s 4 octaves higher than the scale’s 5th note!
Note 5: A major 7th
Now note 5 is even further from 7th than note 1 is from A. So the scale is a major 7th!
Note a is higher than the scale’s 4th, so the 7th and 5th are both higher than the 3rd. So the scale has 3 octaves!
Note 6: A major 3rd
Note 6 is a third higher than the scale’s 5th note! So, the scale is a major 3rd!
Note 7: A minor 7th
Notice that a 3rd notes a note that’s 3 octaves higher than the scale’s 7th note! That’s our B chord:
Notice that every single finger on the 6th finger has an octave above the scale’s 7th note!
You see where all this is going and what the key of the 5th fingerings is for this chart.
So, the scale is a major 7th chord. Each note is 5 octaves higher than the scale’s 5th note!
That means that these 5 note scales are as above as we can get.
So, what is an octave, if not how far is the key above our 1st, 4th and 5th fingerings?
If you play on a musical instrument (or keyboard), you’re familiar with the tuning of it’s parts. So, the pitch range of the notes of a musical instrument (or of a keyboard) is called a scale’s octave range.
