Reading Focus- How do wind instruments produce sound?
All wind instruments depend on vibrating column of air to
Pitch changed by covering and uncovering holes to change
size of column of air.
Reed Instruments- Vibrating reed causes air in tube to
Brass Instruments- Vibrating lips causes air in tube to
Kinds of Flutes- Air from musician causes air in tube to
Reading Focus- How is the length of your vocal chords related to the pitch of your voice?
Pitch- Highness or lowness of a sound.
High pitched sounds have high frequency, low pitch sounds
Hertz- Frequency of sound measured in this unit, cycles per
Octave- Series of eight notes.
Every time you go up one octave, frequency of sound doubles.
Men have longer and thicker vocal chords- deeper voices.
Women can sing at higher pitches.
Children shorter vocal chords- higher pitches than adults.
Guitars- thinner strings=higher notes; thicker strings= lower
Tighter strings = higher notes
Wind Instruments- pitch depends on size of vibrating
column of air. More air=lower pitch; less air=higher pitch.
Amplitude of sound wave heard as loudness
Stringed instruments- loudness depends on how hard you
pluck or bow the strings.
Wind instruments- the harder the musician blows, the
louder the sound.
Percussion instruments- loudness depends on how forcefully
instrument is struck.
Sound Synthesizer- Electronic device that can produce a
large variety of sound.
Music Synthesizers produce sounds using a keyboard or
sound bank. Creates sounds that are like many instruments.
Speech Synthesizers stores sounds that are later combined
to produce words and sentences that sound like a human
