The register key is a key on woodwind instruments that is used to play in the higher registers.
On the clarinet, the register key is used to play in the second register; that is, it raises the pitch of most first-register notes by a twelfth (19 semitones) when pressed. It is positioned above the left thumb hole and is operated by the left thumb. The same key used in combination with the left first finger key which produces the written note A4 (in scientific pitch notation) is used to play B♭4. Some clarinets, particularly bass clarinets and lower, have separate keys, or a more complex key mechanism, to control two or three separate holes for playing B♭, for playing the lower notes of the second register, and for playing the upper notes of the second register.
The octave key is a key on the saxophone or oboe that raises the pitch of most notes by an octave when pressed, so that similar fingerings can be used for two different octaves.
On a saxophone, the octave key is positioned next to the left-hand thumb rest. Pressing the octave key opens the top tone hole in the neck of the saxophone. Alternatively, whenever the G key is fingered, the top tone hole closes and a small tone hole is opened near the top of the body.
Some baritone saxophones, notably those made by Yamaha, also have three octave tone holes. The third one is used to prevent a rough transition from G# to A.
The modern oboe has two octave keys, sometimes three, often interconnected, the one for E5 to G#5 near the left thumb, and the one for A5 to C6 to the right of and above the front keys, depressed by the edge of the left index finger. Oboes are now available with automatic octaves. This involves extra keywork that frees the player from having to bother with an octave key at all. The bassoon has similar keys used by the left thumb, but these are usually only depressed at the attack of notes, or "flicked".
The bassoon is a musical instrument in the woodwind family, which plays in the tenor and bass ranges. It is composed of six pieces, and is usually made of wood. It is known for its distinctive tone color, wide range, versatility, and virtuosity. It is a non-transposing instrument and typically its music is written in the bass and tenor clefs, and sometimes in the treble. There are two forms of modern bassoon: the Buffet and Heckel systems. It is typically played while sitting using a seat strap, but can be played while standing if the player has a harness to hold the instrument. Sound is produced by rolling both lips over the reed and blowing direct air pressure to cause the reed to vibrate. Its fingering system can be quite complex when compared to those of other instruments. Appearing in its modern form in the 19th century, the bassoon figures prominently in orchestral, concert band, and chamber music literature, and is occasionally heard in pop, rock, and jazz settings as well. One who plays a bassoon is called a bassoonist.
The clarinet is a single-reed musical instrument in the woodwind family, with a nearly cylindrical bore and a flared bell.
The oboe is a type of double-reed woodwind instrument. Oboes are usually made of wood, but may also be made of synthetic materials, such as plastic, resin, or hybrid composites.
The recorder is a family of woodwind musical instruments in the group known as internal duct flutes: flutes with a whistle mouthpiece, also known as fipple flutes, although this is an archaic term. A recorder can be distinguished from other duct flutes by the presence of a thumb-hole for the upper hand and seven finger-holes: three for the upper hand and four for the lower. It is the most prominent duct flute in the western classical tradition.
The saxophone is a type of single-reed woodwind instrument with a conical body, usually made of brass. As with all single-reed instruments, sound is produced when a reed on a mouthpiece vibrates to produce a sound wave inside the instrument's body. The pitch is controlled by opening and closing holes in the body to change the effective length of the tube. The holes are closed by leather pads attached to keys operated by the player. Saxophones are made in various sizes and are almost always treated as transposing instruments. A person who plays the saxophone is called a saxophonist or saxist.
A transposing instrument is a musical instrument for which music notation is not written at concert pitch. For example, playing a written middle C on a transposing instrument produces a pitch other than middle C; that sounding pitch identifies the interval of transposition when describing the instrument. Playing a written C on clarinet or soprano saxophone produces a concert B♭, so these are referred to as B♭ instruments. Providing transposed music for these instruments is a convention of musical notation. The instruments do not transpose the music; rather, their music is written at a transposed pitch. Where chords are indicated for improvisation they are also written in the appropriate transposed form.
The sarrusophones are a family of metal double reed conical bore woodwind instruments patented and first manufactured by French instrument maker Pierre-Louis Gautrot in 1856. Gautrot named the sarrusophone after French bandmaster Pierre-Auguste Sarrus (1813–1876), whom he credited with the concept of the instrument, though it is not clear whether Sarrus benefited financially. The instruments were intended for military bands, to serve as replacements for oboes and bassoons which at the time lacked the carrying power required for outdoor marching music. Although originally designed as double-reed instruments, single-reed mouthpieces were later developed for use with the larger bass and contrabass sarrusophones.
The Galician gaita is the traditional instrument of Galicia and northern Portugal.
The bass clarinet is a musical instrument of the clarinet family. Like the more common soprano B♭ clarinet, it is usually pitched in B♭, but it plays notes an octave below the soprano B♭ clarinet. Bass clarinets in other keys, notably C and A, also exist, but are very rare. Bass clarinets regularly perform in orchestras, wind ensembles and concert bands, and occasionally in marching bands, and play an occasional solo role in contemporary music and jazz in particular.
The basset clarinet is member of the clarinet family similar to the usual soprano clarinet but longer and with additional keys to enable playing several additional lower notes. Typically a basset clarinet has keywork going to a low (written) C or B, as opposed to the standard clarinet's E or E♭. The basset clarinet is most commonly a transposing instrument in A, although basset clarinets in C and B♭ and very seldom in G also exist. The similarly named basset horn is also a clarinet with extended lower range, but is in a lower pitch ; the basset horn predates, and undoubtedly inspired, the basset clarinet.
The tenor saxophone is a medium-sized member of the saxophone family, a group of instruments invented by Adolphe Sax in the 1840s. The tenor and the alto are the two most commonly used saxophones. The tenor is pitched in the key of B♭ (while the alto is pitched in the key of E♭), and written as a transposing instrument in the treble clef, sounding an octave and a major second lower than the written pitch. Modern tenor saxophones which have a high F♯ key have a range from A♭2 to E5 (concert) and are therefore pitched one octave below the soprano saxophone. People who play the tenor saxophone are known as "tenor saxophonists", "tenor sax players", or "saxophonists".
The soprano saxophone is a small, high-pitched member of the saxophone family of woodwind instruments invented in the 1840s by Belgian instrument maker Adolphe Sax. Built in B♭ an octave above the tenor saxophone, the soprano is the third-smallest member of the saxophone family, which consists of the soprillo, sopranino, soprano, alto, tenor, baritone, bass, contrabass, and subcontrabass. The soprillo and sopranino are rare instruments, making the soprano the smallest saxophone in common use.
The dulzaina or dolçaina is a Spanish double reed instrument in the oboe family. It has a conical shape and is the equivalent of the Breton bombarde. It is often replaced by an oboe or a double reeded clarinet as seen in Armenian and Ukrainian folk music.
The Western concert flute refers to both the family of transverse (side-blown) woodwind instruments made of metal or wood and its most common member. A musician who plays the flute is called a “flautist” in British English, and a “flutist” in American English.
The alto clarinet is a woodwind instrument of the clarinet family. It is a transposing instrument pitched in the key of E♭, though instruments in F have been made. In size it lies between the soprano clarinet and the bass clarinet. It bears a greater resemblance to the bass clarinet in that it typically has a straight body, but a curved neck and bell made of metal. All-metal alto clarinets also exist. In appearance it strongly resembles the basset horn, but usually differs in three respects: it is pitched a whole step lower, it lacks an extended lower range, and it has a wider bore than many basset horns.
The xaphoon is a chromatic keyless single-reed woodwind instrument invented in 1972, and a registered trademark of its inventor, Brian Lee Wittman. It has a closed cylindrical bore and a very slightly flared bell. The xaphoon has a full chromatic range of two octaves, and overblows at the twelfth like the clarinet.
The ophicleide is a family of conical-bore keyed brass instruments invented in early 19th-century France to extend the keyed bugle into the alto, bass and contrabass ranges. Of these, the bass ophicleide in C or B♭ took root over the course of the 19th century in military bands and as the bass of orchestral brass sections throughout Western Europe, replacing the serpent and its later upright derivatives. By the end of the 19th century, however, it had been largely superseded by early forms of the modern tuba, developed from valved ophicleides.
Altissimo is the uppermost register on woodwind instruments. For clarinets, which overblow on odd harmonics, the altissimo notes are those based on the fifth, seventh, and higher harmonics. For other woodwinds, the altissimo notes are those based on the third, fourth, and higher harmonics. The altissimo register is also known as the high register.
The Boehm system for the clarinet is a system of clarinet keywork, developed between 1839 and 1843 by Hyacinthe Klosé and Auguste Buffet jeune. The name is somewhat deceptive; the system was inspired by Theobald Boehm's system for the flute, but necessarily differs from it, since the clarinet overblows at the twelfth rather than the flute's octave. Boehm himself was not involved in its development.
The Western concert flute family has a wide range of instruments.
