What is the term used to describe the unique sound quality of an instrument created by its harmonics?

• Pitch

• Timbre

• Amplitude

• Frequency

What aspect of sound does the 'fundamental' refer to in wave analysis?

• The highest frequency

• The softest amplitude

• The loudest amplitude

• The lowest frequency

How are octave relationships between pitches generally represented?
