Chôros No. 2 for flute and clarinet; Chôros No. 7 for flute, oboe, clarinet, alto saxophone, bassoon, violin and cello with tam-tam ad lib; Quinteto (em forma de chôros) for flute, oboe, cor anglais, clarinet and bassoon; Carl Maria von Weber: Trio for Piano, Flute and Cello in G minor, Op. 63, J. 259 (1818-19)
The fourth harmonic vibrates at four times the frequency of the fundamental and sounds a perfect fourth above the third harmonic (two octaves above the fundamental). Double the harmonic number means double the frequency (which sounds an octave higher). An illustration in musical notation of the harmonic series (on C) up to the 20th harmonic.

An 88-key piano, with the octaves numbered and Middle C (cyan) and A440 (yellow) highlighted A printable version of the standard key frequencies (only including the 88 keys on a standard piano) Values in bold are exact on an idealized standard piano.
For example, the sound of a piano is produced by striking strings, and the sound of a violin is produced by bowing. All musical sounds have their fundamental frequency and overtones. Fundamental frequency is the lowest frequency in harmonic series. In a periodic signal, the fundamental frequency is the inverse of the period length.
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.
Acoustic resonance is a phenomenon in which an acoustic system amplifies sound waves whose frequency matches one of its own natural frequencies of vibration (its resonance frequencies). The term "acoustic resonance" is sometimes used to narrow mechanical resonance to the frequency range of human hearing, but since acoustics is defined in ...
An 88-key piano, with the octaves numbered and middle C (cyan) and A 4 (yellow) highlighted. A440 is widely used as concert pitch in the United Kingdom [8] and the United States. [9] In continental Europe the frequency of A 4 commonly varies between 440 Hz and 444 Hz. [8]
