Part 1 covers the four basic waveforms (sine, square, triangle, & sawtooth) and harmonics. Please visit http://www.affordableanalogsynths.com for more information.

2. • Sine
• Square
• Triangle
• Sawtooth

3. An harmonic is a component frequency of a
complex wave, that is a whole-number
multiple of the fundamental frequency.

4. A sine wave is the most pure and simple
waveform. All other types of waveforms can
be made by combining multiple sine waves
together.

5. A square wave is composed of a series of sine
waves that decrease in volume. They only
have odd numbered harmonics.

6. A triangle wave contains odd numbered
harmonics. The higher harmonics roll off
quicker than in a square wave.

7. A sawtooth wave has a harsh, buzzing sound. It
is made up of both even and odd harmonics.
