A sound or note of definite pitch is one where a listener can possibly (or relatively easily) discern the pitch. Sounds with definite pitch have harmonic frequency spectra or close to harmonic spectra. [11] A sound generated on any instrument produces many modes of vibration that occur simultaneously. A listener hears numerous frequencies at once.
Pitch is perceived as how "low" or "high" a sound is and represents the cyclic, repetitive nature of the vibrations that make up sound. For simple sounds, pitch relates to the frequency of the slowest vibration in the sound (called the fundamental harmonic). In the case of complex sounds, pitch perception can vary.
An audio frequency or audible frequency (AF) is a periodic vibration whose frequency is audible to the average human. The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch. [1] The generally accepted standard hearing range for humans is 20 to 20,000 Hz.
Logarithmic plot of frequency in hertz versus pitch of a chromatic scale starting on middle C. Each subsequent note has a pitch equal to the frequency of the prior note's pitch multiplied by 12 √ 2. The base-2 logarithm of the above frequency–pitch relation conveniently results in a linear relationship with or :
The fundamental frequency, often referred to simply as the fundamental (abbreviated as f 0 or f 1), is defined as the lowest frequency of a periodic waveform. [1] In music, the fundamental is the musical pitch of a note that is perceived as the lowest partial present.
Bass voice range. [1] Alberti bass in Mozart's Piano Sonata, K 545 opening. Play ⓘ. Bass (/ b eɪ s / BAYSS) (also called bottom end) [2] describes tones of low (also called "deep") frequency, pitch and range from 16 to 250 Hz (C 0 to middle C 4) [3] and bass instruments that produce tones in the low-pitched range C 2-C 4.
Pitch (music), the perceived frequency of sound including "definite pitch" and "indefinite pitch" Absolute pitch or "perfect pitch" Pitch class, a set of all pitches that are a whole number of octaves apart; Relative pitch, the ability to identify a given musical interval between two notes; Pitch accent, a form of accentuation in speech
This notation indicates differing pitch, dynamics, articulation, instrumentation, timbre, and rhythm (duration and onset/order). Traditionally in Western music, a musical tone is a steady periodic sound. A musical tone is characterized by its duration, pitch, intensity (or loudness), and timbre (or quality). [1]
