What is Pitch?

SIM – Pitch/Beat Freq

SIM – Pitch/Beating Freq

pitch depends on length which trombone has the longer wavelength higher pitch a b
Pitch depends on length!Which trombone has the longer wavelength? Higher pitch?AB

Do nodes or antinodes appear at the mouthpiece? Bell?

slide4

Tillery, Physical Science

Do nodes or antinodes appear at the open ends of these pipes?

Which pipes produce the longer wavelength?

Which pipes produce higher pitch?

slide5

Musical instruments create vibrations of the air to produce pitches.

Wind instruments vibrate the air with either a reed or a musician’s buzzing lips.

String instruments vibrate the air with a metal or plastic string.

SIM – Open/Closed Pipe

SIM – Both ends fixed

Trumpet

Tuba

Flute

Sax

Clarinet

Oboe

Trombone

Guitar

Piano

Violin

Viola

Harpsichord

SIM – both ends open

SIM – 1 end open and 1 end fixed

Harmonics - the frequencies that are multiples of a wave’s fundamental frequency.

Ex: if the fundamental frequency is 440 Hz, the harmonics are 880 Hz, 1320 Hz, etc.

Timbre - a musical instrument’s unique sound.

Ex: a clarinet doesn’t sound like a trumpet because it has a different timbre. An instrument's timbre is due to the relative intensities of harmonics present in it’s tone.

Harmonic Series

1st

4th

2nd

5th

3rd

slide8

Along with the 1st harmonic, a wave from a CLARINET has lots of the 3rd, 5th, and 7th harmonics, while only a little of the 2nd, 4th, and 6th harmonics.

Along with the 1st harmonic, a wave from a TRUMPET has lots of the 3rd, while only a little of the 2nd, 4th, and 5th harmonics.

Tillery, Physical Science

When two instruments are each playing a slightly different pitch they sound out of tune.

(SIM1) (SIM2)

Beating Frequency – the wavering sound heard when two slightly different pitches are played together

Beating Frequency = f1 - f2
