This is the ninth song that I'm writing in 10EDL, our main scale for September and October. The next few 10EDL songs will be written in ABC format, with verses, a pre-chorus, and a chorus.
Today's Math I lesson centers around a Desmos lesson that starts out with the Slope Formula. This is combined with a Desmos staple -- Marbleslides. Since the first few slides introduce positive, negative, zero, and undefined slope, this is a great time to write an original song incorporating Sarah Carter's "Slope Dude."
Here's a link to the Mocha code for the song:
10 N=8
20 FOR V=1 TO 2
30 FOR X=1 TO 64
40 READ A,T
50 SOUND 261-N*A,T
60 NEXT V
70 RESTORE
80 NEXT X
90 END

Interestingly enough, my TI music generator program had the Pre-Chorus and Chorus lines start with the same two notes -- (high)C-E, both half notes. I decided to put the title of the song, "Slope Dude," as the lyrics over both sets of half notes.
The chord riffs are D7-Am for the verse, C-D7 for the pre-chorus, and C-Am for the chorus. Even with the same notes leading both the B and C sections, the chords make these parts sound distinct. The chorus melody goes (high)C-E-(high)C-A-E, so the Am chord fits these notes.
In the pre-chorus, the chords repeat, but we might consider adjusting the melody to fit the words. The notes (low)C-F#-(high)C sound good with "Positive," but for "Negative" we might reverse these notes so that the melody is descending, (high)C-F#-(high)C. For "Zero" we can play F#-F#, but suitable notes for "Undefined" are tricky. We might even move "Aaaaaaahhhhhhh!" (a non-melodic scream) up to the channel, or even whisper or rap "Undefined." The new notes for "Negative" and "Zero" can be reflected in the Mocha program, but the code for "Undefined" would be, uh, ill-defined.
The final "Aaaaaaahhhhhhh!" as Slope Dude falls down the cliff can be played without a chord, thus allowing the tonic chord C to be the final chord of the song. Naturally the students in my classes enjoy this part of the song -- and Desmos Marbleslides are always fun.
