Return of the Dread-I
Thinking a scale is a series of intervals, they just happen to be all 2nds. As long as you're aware of the notes, not just blasting a boxed fingering you should be pretty adaptable to intervals when you need them.
Try playing scalar stuff with the notes moved to other octaves and look at what intervals this forms. Putting every other note up or down the octave will give you 7ths or 9ths and 3rds. Try playing a scale but with every other note above the octave i.e. tonic, 2nd above octave, 3rd, 4th above octave, 5th, 6th above octave, 7th, double octave. Work out the intervals between each of those. Between each note in pitch order you'll have 3rds. Move every other one of those down an octave i.e. tonic, 3rd down octave, 5th, 7th down octave, 9th, 11th down octave, 13th. What intervals do you have in between?
It's a bit of an excessive exercise but you could stumble across some cool ways of splitting an idea into a couple of voices.
Now THIS I need to try...
