The Interval Formula started with me calling an octave a “2 by 2” and a fifth a “2 by 1″…
A “2×2” is a mnemonic for one great way of fingering the octave on the bass: two frets over, two strings over. Same principle for the fifth…
While designing the wall chart (AKA the Music Theory Cheat Sheet!), there was color coding involved and arrows and fingerings and the light bulb went off: why not take this concept all the way and apply this idea to all intervals!
The results are great, because once again, thinking of intervals this way (ie: measured on the fret board!) really drives home:
- how notes relate
- the way intervals work
- how strings relate to each other
- best fingerings for intervals
- and it creates a productive way to practice the intervals
The Wall Chart features the interval formula in a color coded fashion, complete with best-practice fingerings, numbers of half steps and most important ways to finger them.
Best way to work with it? pick an interval a day and wrap your mind around it. Theory needs practice (its name, then, is really deceiving 😉 )
I have created 45 minutes of video to go with the wall chart. Overview, exercises and one on the epic IF – Interval Formula.
Interval are the basic building blocks of music theory – if you are able to find them on the fretboard, it really pays off: for scales, triads, chords, but also extensions, alterations, compound intervals… it all starts with the basic intervals within the octave. 0 to 12 half steps. Know them on the bass with good fingering, who and how they work and you have a huge leg up. It is necessary to practice them a bit, so that’s where the chart comes in handy. This video shows practice suggestions. This one gives an overview.
