Since all the modes above contain the exact same notes, only one of them needs to be diagrammed on the fretboard or keyboard to represent all five modes. However, if each of the modes above are thought of individually and scale degrees are not used, it would take 60 fretboard and keyboard diagrams to represent all the modes above in each key (5 modes x 12 keys). Such a needless redundancy is a mistake made by many scale encyclopedias that fail to incorporate the concept of modes. Because of modes, we can condense these 60 potential diagrams into 12: one scale in each key, with each note in each key representing the other modes in their keys. This also makes learning scales and modes much, much simpler as you don’t have to think of modes as completely different scales to be memorized but rather as modes of a single scale. |
