C Δ7 , or major seventh chord on C About this sound Play ( help · info ) . (Photo credit: Wikipedia) |
Triads are built from scale tones. There are both Major seventh and ninth chords (Maj7 or +7 and Maj9) and Minor seventh and ninth chords (m7 and m9):
CDEFGABCDE
C6 = CEGA
C7 = CEGbB
Cmaj7 = CEGB
Cmaj9 = CEGBD
Cm6 = CEbGA
Cm7 = CEbGBb
Cm9 = CEbGBbD
Cm(maj7) = CEbGB
When playing these chords from music with chord symbols, you can play the chord root with your left hand (try to hang around middle C with your left thumb(, and chord tones 3 and 5 with your right hand. From this position, it is possible to play every chord (major, minor, seventh, diminished and augmented):
C = CC/EG
Cmaj7 = CB/EG
C7 = CBb/EG
C6 = CA/EG
Cm(maj7) = CB/EbG
Cm7 = CBb/EbG
Cm6 = CA/EbG
Cdim = CC/EbGb
Caug = CC/EG#
Try playing these voicings in many different keys.
Wikipedia says:
In music composition and arranging, a voicing is the instrumentation and vertical spacing and ordering of the pitches in a chord (which notes are on the top or in the middle, which ones are doubled, which octave each is in, and which instruments or voices perform each). Which note is on the bottom determines the inversion.
Voicing is "the manner in which one distributes, or spaces, notes and chords among the various instruments" and spacing or "simultaneous vertical placement of notes in relation to each other."
