Keyboard layout of each of the 12 major scales.

Shows what each note is and where it lays on the keyboard.

All Major Scales shown here.

Key signatures show where the flats and sharps are designated on each scale.

All Major Scales shown here.

Key signatures shown here without key signatures. These are reflecting where the accidentals would effect the notes within the staff itself (no key signatures).

Circle of 5ths

The order of key signatures that as they relate to each other. They move in an order that adds or takes away sharps/flats. This reflects the direction that is followed on the circle of keys itself.

Major and natural minor scales as they relate to one another.

Same key signature to show how they relate.

That makes it the “relative” minor of that major key, because their key signatures look the same.

This first panel shows keys with sharp accidentals.

More relative minor keys in relation to their major keys.

This panel shows all the scales with the flat accidentals.

Blues Form version 1

This is the simplest version of the 12-bar blues. These are the minimum chord changes that would have to be included in order for it be considered a 12-bar blues.

It is arguable that this is likely not the most common version of the form, but it is the most simple with minimal changes of chords throughout the form.

Blues Form Version 2

This is the version of the blues that musicians and listeners are much more likely to encounter. There is a little more movement, still with a focus primarily on I - IV - V chords of a particular key.

Most of the movement is in the last 4 bars, but the important chords are still found in the form as from the first version.

Blues Form Version 3

There is not much difference here from version 2. It is quite possible to add more substitutions within the form while maintaining the primary “anchor” chords, which can be identified from version 1.
