The fact is, many chords can be played in over 100 different voicings on the guitar. That's ten different voicings, and we haven't even left first position. Chords can be 'voiced' in many different ways.
Multiply by twelve tones, and we're up around 2700.īut we're not done yet. The number of possible inversions will equal the number of tones in the chord, and the 47 chord names represent 228 different inversions. Each chord can have a number of 'inversions', which simply means a different note is in the bass - C-E-G, E-G-C, and G-C-E are all C major chords. (There will actually be more chord names than this, because of enharmonic spellings - Gb7 and F#7 have the same sound on the other hand, there are fewer chord sounds than 47x12, because some, like C6 and Am7 contain identical tones).Ĭhords will vary in the number of pitches they can contain, from just two for power chords to seven for thirteenth chords. Each of those chords can be built on 12 different tones, for a total of over 550 different chord sounds. By my count, there are roughly 47 different chord names used in the tertian system, including power "chords" and various altered and suspended chords used in popular music and jazz. Let me define "lots" a bit more precisely. Almost all popular music follows "tertian" harmony, with chords built in thirds: C-E-G, etc.
