"marked the notes of either the chromatic scale or the diatonic scale, and by setting it to the correct position, the indicated note will be produced when the instrument is blown. Pitch pipes come in all sorts of shapes and sizes. Pitch pipes of this sort were most often used in the 18th and 19th centuries in churches which had no organ to give the opening note of a hymn. They are now quite rare, and hardly ever used for what they were intended, but may still be used as an alternative to a tuning fork. They are also useful"
"Concert pitch Concert pitch is the pitch reference to which a group of musical instruments are tuned for a performance. Concert pitch may vary from ensemble to ensemble, and has varied widely over musical history. In the literature this is also called international standard pitch. The most common modern tuning standard uses 440 Hz for A above middle C as a reference note, with other notes being set relative to it. The term ""concert pitch"" is also used to distinguish between the ""written"" (or ""nominal""), and ""sounding"" (or ""real"") notes of a transposing instrument – ""concert pitch"" here refers to"
"note's particular comb shape of harmonics is detected, the note's pitch can be measured by the vertical position of the comb pattern upon the spectrogram. There are basically two different classes of digital music which create very different demands for a pitch detection algorithm: ""monophonic"" music and ""polyphonic"" music. Monophonic music is a passage with only one instrument playing one note at a time, while polyphonic music can have multiple instruments and vocals playing at once. Pitch detection upon a monophonic recording was a relatively simple task, and its technology enabled the invention of guitar tuners in the 1970s. However,"
"On plucked string instruments with frets, such as the guitar, the pitch of a stopped note is determined by the left hand pressing (stopping) the string at one of the frets. Stopped note On string instruments, a stopped note is a note whose pitch has been altered from the pitch of the open string by the player's left hand pressing (stopping) the string against the fingerboard. On bowed string instruments, a stopped note is a played note that is fingered with the left hand, i.e. not an open string. This assists with tone production, the addition of vibrato, and sometimes"

This system is called scientific pitch notation (aka American Standard Pitch Notation), and ties each letter/number combination to a specific frequency: In some regions of Europe"
"Scientific pitch Scientific pitch, also known as philosophical pitch, Sauveur pitch or Verdi tuning, is an absolute concert pitch standard which is based on middle C (C4) being set to 256 Hz rather than 261.62 Hz, making it approximately 37.6 cents lower than the common A440 pitch standard. It was first proposed in 1713 by French physicist Joseph Sauveur, promoted briefly by Italian composer Giuseppe Verdi in the 19th century, then advocated by the Schiller Institute beginning in the 1980s. Scientific pitch is not used by concert orchestras but is still sometimes favored in scientific writings for the convenience of"

In well-tempered systems (as used in the time of Johann Sebastian Bach, for example), different methods of musical tuning were used. Almost all of these systems have one interval in common, the octave, where the pitch of one note is double the frequency of another. For example, if the A above middle C is 440 Hz, the A an octave above that is . In atonal, twelve tone, or musical set theory a ""pitch"" is a specific frequency while a"

For an instrument in equal temperament tuned to the A440 pitch standard widely adopted in 1939, middle C has a frequency around 261.63 Hz (for other notes see piano key frequencies). Scientific pitch notation was originally proposed in 1713 by French physicist Joseph Sauveur and based on the numerically convenient frequency of 256 Hz for middle C, all C's being powers of two. After the A440 pitch standard was adopted by musicians, the Acoustical Society of America published new frequency tables for scientific use. A movement to restore the older A435 standard has used"
"notes from natural sources are usually a complex mix of many frequencies. Accordingly, theorists often describe pitch as a subjective sensation. Specific frequencies are often assigned letter names. Today most orchestras assign Concert A (the A above middle C on the piano) to the frequency of 440 Hz. This assignment is somewhat arbitrary; for example, in 1859 France, the same A was tuned to 435 Hz. Such differences can have a noticeable effect on the timbre of instruments and other phenomena. Thus, in historically informed performance of older music, tuning is often set to match the tuning used in the"

The tuner then displays the pitch in relation to the desired pitch, and indicates whether the input pitch is lower, higher, or equal to the desired pitch.

Tuners with a needle are often supplied with a backlight, so that the display can be read on a"

In standard Western equal temperament, the notion of pitch is insensitive to ""spelling"": the description ""G double sharp"" refers to the same pitch as ""A""; in other temperaments, these may be distinct pitches. Human perception of musical intervals is approximately logarithmic with respect to fundamental frequency: the perceived interval between the pitches ""A220"" and ""A440"" is the same as the perceived interval between the pitches ""A440"" and"
"Clef A clef (from French: ""clé"" ""key"") is a musical symbol used to indicate the pitch of written notes. Placed on a stave, it indicates the name and pitch of the notes on one of the lines. This line serves as a reference point by which the names of the notes on any other line or space of the stave may be determined. There are three types of clef used in modern music notation: ""F"", ""C"", and ""G"". Each type of clef assigns its reference note to a line (and in rare cases, a space) depending on its placement on"

The left hand fingertips stop the strings along their length, determining the pitch of each fingered note.

"Pitch detection algorithm A pitch detection algorithm (PDA) is an algorithm designed to estimate the pitch or fundamental frequency of a quasiperiodic or oscillating signal, usually a digital recording of speech or a musical note or tone. This can be done in the time domain, the frequency domain, or both. PDAs are used in various contexts (e.g. phonetics, music information retrieval, speech coding, musical performance systems) and so there may be different demands placed upon the algorithm. There is as yet no single ideal PDA, so a variety of algorithms exist, most falling broadly into the classes given below. A"

Pulling out this graduated strip of wood causes the inner end of the movable piece to rest on the string, shortening or lengthening its length so that the desired pitch will be sounded.

"Western music, any note is either separated from another by a whole number of perfect fifths, or is in the same pitch class as such a note. In these scales, therefore, the interval between any pair of notes can be formed either by adding a whole number of fifths to, or subtracting them from, a whole number of octaves, or by subtracting a whole number of octaves from a whole number of fifths. A regular tuning of such scales, therefore, can be constructed from a single chain of fifths, the pitch of any note being determined by that of a"
"Scientific pitch notation Scientific pitch notation (or SPN, also known as American standard pitch notation (ASPN) and international pitch notation (IPN)) is a method of specifying musical pitch by combining a musical note name (with accidental if needed) and a number identifying the pitch's octave. Although scientific pitch notation was originally designed as a companion to scientific pitch (see below), the two are not synonymous. Scientific pitch is a pitch standard—a system that defines the specific frequencies of particular pitches (see below). Scientific pitch notation concerns only how pitch names are notated, that is, how they are designated in printed"
"Electronic tuner In music, an electronic tuner is a device that detects and displays the pitch of musical notes played on a musical instrument. ""Pitch"" is the highness or lowness of a musical note, which is typically measured in Hertz. Simple tuners indicate—typically with an analog needle-dial, LEDs, or an LCD screen—whether a pitch is lower, higher, or equal to the desired pitch. In the 2010s, software applications can turn a smartphone, tablet, or personal computer into a tuner. More complex and expensive tuners indicate pitch more precisely. Tuners vary in size from units that fit in a pocket to"
"Pitch (music) Pitch is a perceptual property of sounds that allows their ordering on a frequency-related scale, or more commonly, pitch is the quality that makes it possible to judge sounds as ""higher"" and ""lower"" in the sense associated with musical melodies. Pitch can be determined only in sounds that have a frequency that is clear and stable enough to distinguish from noise. Pitch is a major auditory attribute of musical tones, along with duration, loudness, and timbre. Pitch may be quantified as a frequency, but pitch is not a purely objective physical property; it is a subjective psychoacoustical attribute"

For example, A (the reference pitch) is the 49th key from the left end of a piano (tuned to 440 Hz), and C (middle C) is the 40th key. These numbers can be used to find the frequency of C: The intervals of 12-TET closely approximate some intervals in just intonation. The fifths and fourths are almost indistinguishably close to just, while thirds and sixths are further away. In the following table the sizes of various just intervals"
"Musical note In music, a note is the pitch and duration of a sound, and also its representation in musical notation (♪, ♩). A note can also represent a pitch class. Notes are the building blocks of much written music: discretizations of musical phenomena that facilitate performance, comprehension, and analysis. The term ""note"" can be used in both generic and specific senses: one might say either ""the piece 'Happy Birthday to You' begins with two notes having the same pitch"", or ""the piece begins with two repetitions of the same note"". In the former case, one uses ""note"" to refer"

"Pitch axis theory Pitch axis theory is a musical technique used in constructing chord progressions. The tonic is used as the bass note, and melodic scales are chosen according to the chords that lie beneath them. ""A variety of scales or modes are used, all built around the same tonic pitch."" The pitch axis is the pitch common and most important to the tonic of the initial key and all chords in a chord progression. Each of the seven modern modes is obtainable from any of the others by a sequence of diatonic rotations; by such a sequence, for example,"

When there is more than one chain, the pitches of the notes in one chain relative to those of another are completely determined by any single interval between any pair of notes, of which one belongs to the first chain and the other to the second.

"of the typical spacing of the resonances, these frequencies are mostly limited to integer multiples, or harmonics, of the lowest frequency, and such multiples form the harmonic series (see harmonic series (mathematics)). The musical pitch of a note is usually perceived as the lowest partial present (the fundamental frequency), which may be the one created by vibration over the full length of the string or air column, or a higher harmonic chosen by the player. The musical timbre of a steady tone from such an instrument is strongly affected by the relative strength of each harmonic. A ""complex tone"" (the"

However, tuning has varied over time, geographical region, or instrument maker. In 17th-century Europe, tunings ranged from about A-374 to A-403, approximately two to three semitones below A-440. Historical examples exist of instruments, tuning forks, or standards ranging from A-309 to A-455.3, a difference of almost six semitones. Although the official standard today is A-440, some orchestral groups and chamber groups prefer to tune a little higher, at A-442 or"

To differentiate two notes that have the same pitch class but fall into different octaves, the system of scientific pitch notation combines a letter name with an Arabic numeral designating a specific octave. For example, the now-standard tuning pitch for most Western music, 440 Hz, is named a′ or A4. There are two formal systems to define each note and octave, the Helmholtz pitch notation and the scientific pitch notation. Letter names are modified by the accidentals."

Likewise, if a string tuned to 220 Hz (with a harmonic at 440 Hz) is played together with a string tuned at 442 Hz, the same 2 Hz beat is heard. Because pianos typically have multiple strings for each piano key, these strings must be tuned to the same frequency to eliminate beats. The pitch of a note is determined by the frequency of vibrations. For a vibrating string, the frequency is determined by the string's length, mass, and tension. Piano strings are wrapped around tuning pins, which are turned to adjust"
