Question: What's the difference between Drop 2 and Drop 3?
Drop voicings work by taking a close (stacked) four-note chord and dropping one note down an octave.
Drop 2 means you drop the second-highest note. So if your close voicing reads (bottom to top) root–3rd–5th–7th, dropping the second-highest note (the 5th) gives you root–5th–7th–3rd. The 5th moves down an octave and lands below the 7th.
Drop 3 means you drop the third-highest note. Starting from root–3rd–5th–7th, you drop the 3rd down an octave, giving you 3rd–root–5th–7th (reading bottom to top after the drop).
The practical difference: Drop 2 voicings are more open and spread across the fingerboard — they're the workhorse of jazz guitar comping because they sit naturally under the hand and leave room for a melody note on top. Drop 3 voicings are wider still and tend to sound darker or more spacious because the bass note and the notes above it are further apart.
You can generate both from Chord Lab once GMI Premium launches — it will show you Drop 2, Drop 3, and Drop 2+4 across all chord types and inversions.
