A basic approach to compose a song is to repeat a sequence of
tones again and again. If this is done correctly, the restatement
of the sequence of tones will help to make the musical piece easier
to remember and more recognizable. Musical restatements are very
similar to geometric transformations. A geometric figure like a
triangle can be relocated while preserving its size and shape.
If musical notes are placed at the vertices of the triangle below
and the triangle is moved horizontally from position A to position
B. What musical notes should be in position B?
In musical application, the notes will repeat accordingly as shown
If the triangle in position I reflects to position II, what is the
musical reflection of the notes?
Estimate the answer:
notes will repeat
notes will reflect horizontally.
notes will reflect vertically.
