Additive Synthesis

• A synthesis technique that creates a periodic signal by adding sinusoids together.

Amplitude

• The size of a signal.

Bass Clef

• Also called F clef. Indicates the note on the fourth line is F below middle C.

Bit

• Short for “binary digit”. A bit takes on only the value of 0 or 1.

Byte

• Eight consecutive bits.

Chord

• A collection of simultaneously played tones.

Clef

• The sign written at the beginning of a staff to indicate pitch.

Fundamental

• A mathematical quantity describing the repetition rate of a periodic signal.

Hertz

• Units of frequency or repetition rate, measured in periods per second.

Loudspeaker

• A device that turns electrical energy into sour energy.

Melody

• A sequence of notes that make up a piece of music.

Microphone

• A device that turns sound energy into electrical energy.

Periodic Signal

• A signal that exactly repeats at regular intervals.

Pitch

• The perceived frequency of a sound.

Rate of Decay

• A number that describes the way an exponential function decreases over time.

Score

• Notation showing all parts or instraments.

Signal

• A pattern or variation that contains information, usually denoted as s(t).

Sound Signal

• A pattern or variation in air molecules that a sound makes.

Tempo

• The speed of a piece of music.

Spectrum

• A plot of periodic signal’s sinusoidal components.
