Cadence- two chord progression that occurs at the end of a phrase

Conclusive Cadence- anything ending on a tonic triad

Inconclusive Cadence- sounds incomplete(half/deceptive) not ending on tonic Half- any chord going to a V

Phrygian Half- IV- V
Authentic- V (or vii at least that’s what musictheory.net says ) going to I
Perfect Authentic (PAC)- 3 conditions

1. Must be V chord first rather than vii

2. Must both be in root position

3. Last chord must have the tonic at the top of the chord

Imperfect- everything else

Plagal-IV(iv) to I(i)

Deceptive- V to anything else except I(usually vi?)

Cadential extension- delaying cadence by adding additional things to the closing phrase

Coda- a musical selection that closes the harmonic/melodic phrases reinforce the final cadence

Codetta-marks end of sonatas, ends in a perfect cadence; not necessarily signals the end of the piece; a smaller version of a coda

Contour-shape of the melody

Countermelody-sequence of notes that looks like the melody but isn’t and it’s meant to be played with the leading melody

Elision (phrase elision)-last note of first phrase serves to be the first note of the second phrase

Fragment (fragmented motive)-using part of melodic line rather than the entirety-
