Variation on a Simple Tune

Filed under: Uncategorized — m759 @ 11:20 AM

The previous post discussed a tune ending in the following
sequence of notes (symbols as in a Wikipedia article):

C#4  B4  A4  E4  G4 .

(This sequence was approximated in that post by integers
representing the relative frequencies of the notes:  5  9  8  6  7 .)

Yesterday’s simple tune may suggest to some a similar refrain:

D4    E4    C4   C3   G3 .

This is, as a helpful page at Ars Nova Software explains,
the theme from “Close Encounters of the Third Kind.”

The notes of the just intonation major scale:

The corresponding ratios from Close Encounters are…

9/8   5/4   1/1   1/2   3/4 , or, in whole numbers, 9  10  8  4  6.

These numbers also correspond, as in yesterday’s post, to the notes

B4  C#5  A4  A3  E4 .

9  10  8  4  6  for Close Encounters.

“And you can tell everybody this is your song…”
