[S:1] A Heartbeat (Heartbeat.mp3 0:32) The well known rhythmic "lub-dub" of a beating heart.
[S:2]Where does it start? This series of sound examples N=0,1,...,8 performs the rhythmic patterns shown in the figure. When N=0, all notes are struck equally. Which note does the pattern appear to begin on? For N=1,...,7, the Nth note is emphasized. How many different starting positions are there? For N=8, All notes are struck equally, but the timing between notes is not exact. Does timing change the perceived starting position?
[S:3]Regular Interval 750 (RegInt750.mp3 0:15). This is a series of identical clicks with exactly T=750 ms between each click. Does the sequence sound identical? Observe the natural tendency of the perceptual system to collect the sounds into groups of 2, 3, or 4.
[S:4]Ever-Ascending Sound (EverRise.mp3 5:19) The pitch of this organ-like sounds rises continuously, yet paradoxically returns to the place where is started.
[S:5]Maple Leaf Rag (MapleLeafRag.mp3 1:52) Scott Joplin's (1868-1917) most famous ragtime piano piece, the Maple Leaf Rag was one of the first instrumental sheet music hits in America, selling over a million copies. Performed by the author. See Sect. 1.7.
[S:6]Maple Tap Rag (MapleTapRag.mp3 1:51). Audio beat tracking of the Maple Leaf Rag is demonstrated by superimposing a burst of white noise at each detected beat. In terms of the musical score, the detected beat coincides with the eighth note pulse. See Sect. 8.3.2 for more detail.
[S:7] Soul (Soul.mp3 2:47). Soul is used to illustrate various sound manipulations throughout Rhythm and Transforms in a "hard rock" context.

The song is used (and abused) with permission of the authors.
[S:8]Julie's Waltz (JuliesWaltz.mp3 2:39). Julie's Waltz is used in Chap. 11 as a case study showing how beat-based feature scores can display detailed information about the timing and timbre of a performance. Julie's Waltz, written by Mark Schatz, appears in Brand New Old Tyme Way . The song is used with permission of the author.
