Koncovka, a Slovak overtone flute

An overtone flute is a type of a flute that is designed to play in the upper harmonics, typically well above the two or three harmonics that are the practical limit for most woodwind instruments.

Contents

An overtone flute has either no tone holes, [2] or relatively few tone holes for a woodwind instrument. [3] To make melodies, one plays it high into the overtone series. One series of harmonics is achieved by overblowing with the end of the tube open and another is achieved with the end closed; when the end of the flute is closed, the key drops by one octave and only the uneven harmonics can pop out. This means that overtone flutes without tone holes will produce mostly the notes present in the natural scale, whilst certain notes can be bent a bit by partially covering the end of the flute.

Overtone flute tubes typically have a relatively long resonating chamber compared to their inner diameter or cross sectional area, which encourages the instrument to resonate in the higher harmonics. An overtone flute in the key of G, with an inner diameter of 1", will require more effort to play higher harmonics than an overtone flute in the same key, with an inner diameter of 1/2". For example, a ratio of 1 : 30 - Inner Diameter : Length allows for very high harmonics to be played with little effort.

<span class="mw-page-title-main">Harmonic</span> Wave with frequency an integer multiple of the fundamental frequency

In physics, acoustics, and telecommunications, a harmonic is a sinusoidal wave with a frequency that is a positive integer multiple of the fundamental frequency of a periodic signal. The fundamental frequency is also called the 1st harmonic; the other harmonics are known as higher harmonics. As all harmonics are periodic at the fundamental frequency, the sum of harmonics is also periodic at that frequency. The set of harmonics forms a harmonic series.

<span class="mw-page-title-main">Overtone</span> Tone with a frequency higher than the frequency of the reference tone

An overtone is any resonant frequency above the fundamental frequency of a sound. In other words, overtones are all pitches higher than the lowest pitch within an individual sound; the fundamental is the lowest pitch. While the fundamental is usually heard most prominently, overtones are actually present in any pitch except a true sine wave. The relative volume or amplitude of various overtone partials is one of the key identifying features of timbre, or the individual characteristic of a sound.

Overblowing is the manipulation of supplied air through a wind instrument that causes the sounded pitch to jump to a higher one without a fingering change or the operation of a slide. Overblowing may involve a change in the air pressure, in the point at which the air is directed, or in the resonance characteristics of the chamber formed by the mouth and throat of the player.

The stub-ended Swanson tonette is a small, end-blown vessel flute made of plastic, which was once popular in American elementary music education. Though the tonette has been superseded by the recorder in many areas, plastic Tonettes are still in use in elementary schools around the nation due to their price, durability, and simplicity. The range of the tonette is from C4 to D5. A skilled player can produce notes above the principal register by overblowing and half-covering holes. Similar instruments are the song flute, flutophone, and precorder.

The willow flute, also known as sallow flute, is a Nordic folk flute, or whistle, consisting of a simple tube with a transverse fipple mouthpiece and no finger holes. The mouthpiece is typically constructed by inserting a grooved plug into one end of the tube, and cutting an edged opening in the tube a short distance away from the plug.

Acoustic resonance is a phenomenon in which an acoustic system amplifies sound waves whose frequency matches one of its own natural frequencies of vibration.

In music, the undertone series or subharmonic series is a sequence of notes that results from inverting the intervals of the overtone series. While overtones naturally occur with the physical production of music on instruments, undertones must be produced in unusual ways. While the overtone series is based upon arithmetic multiplication of frequencies, resulting in a harmonic series, the undertone series is based on arithmetic division.

The koncovka is a Slovak duct-blown overtone fipple flute without finger holes, traditionally played by shepherds. The koncovka is played by closing and opening the bottom hole of the flute.

Traditional koncovka melodies use the partial Lydian scale available on this instrument.
