NCT in the melody that consists of:
- any note longer than a beat in duration
- notes of any duration followed by a leap and not part of a delayed resolution
what are the 2 key characteristics of harmonic tensions?
- used in conjunction with the vertical chord structure
2. the tension duration should mirror the melody and follow the appropriate voicing rules.
why should you include the harmonic tensions in the chord symbols?
to benefit the rhythm section and any improvising musician
within triads, when are the sixth and 7th considered tensions used in the melody
they can be used as melodic passing tones in a melody that moves against a sustained triad
within triads, when are the sixth and 7th considered tensions used in the the harmony
they aren’t, when they are included in the harmonic voice the triad becomes a four note chord

what tensions are always available on a dominant 7th chord
Tb9, T9, T#9, T#11, Tb13, T13
Tb5 - when not already a tension by chord symbol
what should you avoid combining with a T9 on a dominant 7th chord
Tb9 or T#9
what should you avoid combining with a T13 on a dominant 7th chord
Tb13
what 2 tones should you avoid combining with a 5 on a dominant 7th chord
- Tb13 (this replaces 5)
2. b5
what tensions are always available on an augmented 7th chord
T9, T#11
what tensions are always available on an dominant 7th sus 4 chord
T9, T13
somtimes T10
what tensions are available on a diminished 7th chord
tensions aren’t numerically labeled.
each tension creates the same sets of intervals with the chord tones.
available tensions depend on chord scale and context
a T13 is not available on minor 7th chords having what function
tonic or subdominant
what is not available on a III-7
T9
what tension can be written on IMaj7 for dramatic outcome
T#11
what half step tensions are the exception to the rule
Tb9 on a dominant 7 (b9) chord
Tb13 on a dominant 7 (b13) chord
the mode allows for the tension because it is diatonic to the mode
