The diatonic scale has 7 different “modes”. Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian and Locrian. Ionian scales start on the tonic note (C major Ionian scale starts from C to C), Dorian scales start on the super tonic (C major Dorian starts from D to D), Phyrgian scales start from the mediant (C major Phyrgian starts from E to E), Lydian starts from the subdominant ( C major Lydian starts from F to F), Mixolydian starts from the dominant ( C major Mixolydian starts from G to G), Aeolian starts from the submediant ( C major Aeolian starts from A to A) and Locrian starts from the leading tone (C major Locrian starts from B to B). This is sort of like how math has numbers. I will use this page to memorize all the diatonic modes.
