Fretting your cigar box guitar diatonically can be a nice alternative when building. But a lot of people are not clear on what it is.
A diatonic scale sounds like the familar “DO-RE-MI” scales we learned as kids. It contains only the “whole” tones of the scale, with no “accidentals” (sharp or flat notes that are outside of the primary scale). A chromatic scale on the other hand gives you all of the “extra” notes as well, and though it sounds much less pleasant when played from low to high, it presents a lot more flexibility when playing music.
