Other Altered Major Scales

Is it a mode or an altered scale

If it’s not a mode, it’s an altered scale. So any mode that has a major sound but changes one note, or adds a note, will still be normal major if it also has maj7.

This is major, in any key:

1 2 3 4 5 6 maj7 8

All of the scales below are not major scales. At least one note is changed. But they all retain the major sound because they all have 3 and maj7.

  • 1 b2 3 4 5 6 maj7 8
  • 1 2 3 4 5 #5 6 maj7 8
  • 1 2 3 #4 5 6 maj7 8
  • 1 2 3 4 5 6 (b)7 maj7 8
  • 1 2 #2 3 4 5 6 (b)7 maj7 8
  • 1 2 3 4 #4 5 6 maj7 8

One of these scales is not an altered scale because it turns into a mode. Can you spot the mode?

The rest have a variety of names, none of which are the least bit important. However, when you see the same number twice in a row, like 2 and #2, there is a passing tone added. And there is absolutely no rule about now many passing tones can be in a scale.
