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.
