Music theory question for any cats on here who might know. Trying to find out if there are any fretboard maps online that show the intervals of the keys shown out across the fretboard. You know how if you are on the Root then the fourth is directly under that and the 5th is above the Root. I am trying to memorize whatever interval you are on what interval is directly below the note and what is directly above the note you are on at any given time. Like say I am rocking the tonic and the guitarist is hitting a major 6th chord and I want to highligh that 6th interval then I know ok I am pounding on the Root so the closest sixths are one fret above and two frets towards the neck or two frets directly below and one fret over towards the nuts kind of thing. I know it may be crazy to think that way and that is 12 intervals to memorize what is directly above and below each but thinking the pattern could be memorized and make the fretboard a bit more memorizable then just shift that pattern to what root note you are on. 1, 4, and 5 and the octave are so burned into memory from being so common in songs I am just wanting to branch out I suppose.
