Preliminary Examples
A lot of musical information can be recognized from short excerpts.
1a: Beethoven: 5. symphony (1999ms)
1b: Schubert: Credo from Mass in Bb (2124ms)
1c: Aqua: Barbie Girl (1500ms)

Timbre Changes
The timbre of an instrument changes across the registers. Notice how "unnatural" the processed tones (2b, 2c) sounds. The original (2a) is a Sony Rollins Saxophone Tone.
2a: Original tone
2b: Transposed one octave up
2c: Transposed one octave down
Short Term Recognition
How long time do you actually need to recognize the music? Durations are given in milliseconds (ms) or seconds (s).
Eric Clapton: Tears in Heaven
3a: 134ms
3b: 380ms
3c: 960ms
3d: 3668ms
3e: 25s
Sarah McLahlan: When She Loved Me
4a: 1021ms
4b: 3297ms
4c: 9s
4d: 17s
4e: 32s
Salience
Modulation is one of the most powerful examples of musical salience.
5a: Various Artists: We are the World
Salient Musical Parameters
Each of the musical parameters can be salient.
Melody
6a: Beethoven: 9. symphony, 4. mov.
6b: Dvorak: 9. symphony, 2. mov.
Harmony
7: Stevie Wonder: You are the Sunshine of my Life
Rhythm
8a: Beethoven: 5. symphony, 1.mov.
8b: Beethoven: 5. symphony, 3. mov.
Dynamics
9a: Grieg: A-minor Concerto
9b: Reversed piano tone
Salient Voices
Voices can have some very salient features, making them easily recognizable.
10a: Various Artists: We are the World
10b: John Lennon: Yesterday
10c: Bob Dylan: Blowing in the Wind
10d: Ella Fitzgerald: Dream a Little Dream of Me
10e: Louis Armstrong: Summertime
Salient Piano Sound
Even though a piano is a ballistic instrument, piano sound can be very unique and distinct for a style, composer or performer.
11a: Mozart: Piano Concerto K488, 1
11b: Stockhausen: Klavierstücke I
11c: Debussy: Pour remercier la pluie au matin
11d: Keith Jarrett: K?ln Concert, III

Timbre Analysis and Synthesis
A saxophone tone played by Sony Rollins. Notice the timbre change and slight increase in pitch. Also interesting is the fact that about 60 partials are needed to adequately reproduce the sound.
