Frequency & Pitch

This lesson is part of the Fundamentals of Sound & Music module.

Objectives

Students will be familiar with waveform diagrams.
Students will understand how frequency relates to the aural concept of pitch.
Students will understand how frequencies of multiple waveforms interact.
Students will understand the difference between a simple and complex soundwave.
Students will understand the concept of timbre and be able to describe different timbres.
Students will be familiar with different waveform types (sawtooth, square, etc.) and understand their relationship to timbre and pitch.
Students will understand the difference between absolute and relative pitch.

Discussion and definition of frequency, pitch, amplitude, dynamics and waveform diagrams
Investigation of variables using waveform diagrams
Demonstration of the combination of two sounds, and the visualization of the process as waveform diagrams
Use of an oscilloscope to analyze and compare different sounds
