Guitar Octaves

Guitar octaves are a very effective way to see how notes on the guitar are organized. The really cool thing is that they are consistent for every tone. Once you know the shapes for any given tone, not only are they the same for every other tone, but they always cycle in the same order (just like chord forms). This is the bare bones for standard tuning. The grid everything wraps around.

An octave is an interval of an 8th, such as C to C, or A to A. It is a frequency doubling or halving of a tone (twice as fast or slow).

In Western music, scales are typically heptatonic (7 tones). Therefore, the completion of a scale, whether Major or minor or other, is the 8th, which is the same letter name, or tone, as the first. (Oct- means eight). Within an octave are 13 tones (13th completing), and 12 half steps.

In cultures using Pentatonic scales (5 tone scales) as their primary melodic & harmonic material, the 'octave' could be called a 6th, rather than an 8th. In 12 tone music (dodecaphonic), the 'octave' could be called a 13th.

Here is a snapshot of all 7 of the octave shapes with 1 double octave (8 total, unless you can reach some more double octaves - go easy & don't hurt your hand).

Often we fret these & try to MUTE the other strings, so we can move them around (completely rock out).

Some are more difficult to MUTE & MOVE than others. Here is some TAB for showing which octave shapes we consider more & less useful (depending on how you use them):
