Clarification/Review of Homework for Friday 4/19

Your homework for tomorrow (Friday 4/19), as was announced in class, is to:

1) Compose a one-measure, two part set of complimentary rhythms (like we did in class Wednesday, but with two parts rather than four).  Since you are notating rhythms only, you can write this on any kind of paper--it does not have to be staff paper.

2) In your copy of the harmonized version of Amazing Grace (if you lost it, there's a link to it in the previous post), add the superscript numbers which indicate inversions for those chords which are inverted (i.e., the root of the chord is not in the bass, the lowest-sounding note).

Remember, for a first-inversion triad-based chord, put a superscript "6" after the Roman numeral. For a second-inversion triad-based chord, it's a 6 over a 4.  (You can see better in the video.)  When typing in a program where superscript numbers aren't available, or stacking numbers isn't a possibility, things are often written like this"  I 6 (for a first inversion I chord) and I 6/4 (for a second inversion I chord).


For 7th chords, the numbering for inversions is different, because the intervals are different, given that seventh above the root makes for additional intervals.

Using V7 chords as an example, the we label inversions as follows:

  • V7 (root position)
  • V6/5 (1st inversion, 3rd in the bass)
  • V4/3 (2nd inversion, 5th in the bass)
  • V2 (3rd inversion, 7th in the bass)
