1
00:00:00,500 --> 00:00:03,233
More notes do not always mean a faster
tempo.

2
00:00:03,483 --> 00:00:07,750
Here, in four-four time, the quarter-note
pulse is sixty beats per minute.

3
00:00:08,000 --> 00:00:09,817
That is one beat each second.

4
00:00:10,067 --> 00:00:12,200
Quarter notes: one note per beat.

5
00:00:13,000 --> 00:00:17,000
[Synthetic tones: 1 per beat]

6
00:00:17,500 --> 00:00:19,933
Eighth notes: two equal notes per beat.

7
00:00:21,000 --> 00:00:25,000
[Synthetic tones: 2 per beat]

8
00:00:25,500 --> 00:00:28,317
Sixteenth notes: four equal notes per
beat.

9
00:00:29,000 --> 00:00:33,000
[Synthetic tones: 4 per beat]

10
00:00:33,500 --> 00:00:36,783
Only note density changes here; the tempo
does not.

11
00:00:37,033 --> 00:00:41,267
These synthetic tones illustrate timing,
not an acoustic performance.

12
00:00:41,517 --> 00:00:45,033
The narration is synthetic too.
