The outcome of the lesson: The understanding musical "height" and pitch measuring unit

3 Distinctive characteristics of sound

• Vibrations: sinusoid description (concepts of periodicity, amplitude, terminology description)
• Pitch, intensity, timbre
• Pitch

The attribute of sound perception that gives the impression of (musical) “height”, enabling us to arrange sounds from low to high.

The frequency of the vibration (how many cycles in a second), measured in Hz.

• The frequency range of human hearing
• Musical notes expressed in Hz (picture)
• Different frequency ranges for different instruments
