musical tone is a steady periodic sound characterized by duration pitch intensity (or loudness) timbre (or quality)
duration is an amount of time or how long or short a note, phrase, section, or composition lasts is the length of time a pitch, or tone, is sounded
timbre (tone color/quality) is the perceived sound quality of a musical note, sound or tone physical characteristics of sound that determine the perception of timbre include frequency spectrum envelope
envelope describes how a sound changes over time amplitude (volume) frequencies pitch
pitch is a perceptual property of sounds that allows their ordering on a frequency-related scale. is the quality that makes possible to judge sounds as "higher" and "lower" (?) in the sense associated with musical melodies.
amplitude of a periodic variable is a measure of its change in a single period (such as time or spatial period).
loudness is the subjective perception of sound pressure That attribute of auditory sensation in terms of which sounds can be ordered on a scale extending from quiet to loud
frequency spectrum Any signal that can be represented as a variable that varies in time has a corresponding frequency spectrum
frequency is the number of occurrences of a repeating event per unit of time
spectrum is a condition that varies across a continuum
audio signal is a representation of sound for analog signals uses a changing level of electrical voltage for digital signals uses a series of binary numbers has an audio frequency ranging (roughly) 20 to 20,000 Hz which corresponds to the lower and upper limits of human hearing characterized by bandwidth nominal level power level in decibels (dB) voltage level
bandwidth is the difference between the upper and lower frequencies in a continuous band of frequencies measured in hertz
nominal level is the operating level at which an electronic signal processing device is designed to operate.
electric power is the rate at which electrical energy is transferred by an electric circuit. units of measurement is the watt
unit of measurement is a definite magnitude of a quantity
quantity (or amount) is a property that can exist as a magnitude illustrating continuity multitude illustrating discontinuity
multitude is what cannot be classed under any other distinct category, except for it's shared fact of existence.
magnitude is a property that determines whether the object is larger or smaller than other objects of the same kind
size is a concept abstracted from the process of measuring by comparing a longer to a shorter is the magnitude or dimensions of a thing geometrical size (or spatial size) can refer to linear dimensions (length, width, height, diameter, perimeter), area, or volume. Size can also be measured in terms of mass, especially when assuming a density range.
property is any characteristic that applies to a given set
