D Ionian — Chicago Tuning Banjo

D Ionian is 7 notes to the octave (modes family), drawn here across the Chicago Tuning Banjo's DGBE strings with every D marked, so home stays visible from anywhere in the pattern.

Bright, resolved, and stable. The foundation of Western tonal music and the most common mode in pop, classical, folk, and jazz.

Heard in: Pop, classical, country, folk, gospel — the default major tonality of Western music.

Because these four strings are the guitar's top four, patterns a guitarist already owns land here unchanged. The work is rhythmic rather than geographical: making the pick articulate every note the head refuses to sustain.

Run it against a click at a tempo where every note gets the same weight. On a banjo an uneven scale is audible immediately — the instrument gives you no sustain to hide behind.
