Piccolo in the context of "Alto flute"

Program music or programmatic music is a type of instrumental music that attempts to musically render an extramusical narrative or description of some aspect of world. The term was invented in the 19th century by Franz Liszt, who himself composed a great deal of program music. However, as Liszt himself noted, program music had been written for centuries before his time.

To give an example, Ludwig van Beethoven's Sixth Symphony narrates a visit to the countryside, portraying in succession a happy arrival, a quiet moment by a brook, an encounter with dancing peasants, a thunderstorm, and the peasants' song of thankgiving when the storm is over. Program music is often written so that the notes themselves convey, at least to some degree, the meaning of what is portrayed; thus the thunderstorm in Beethoven's symphony includes loud timpani strokes to convey the thunder and shrill piccolo music to depict the shrieking winds.

The Western concert flute can refer to the common C concert flute or to the family of transverse (side-blown) flutes to which the C flute belongs. Almost all are made of metal or wood, or a combination of the two. A musician who plays the flute is called a “flautist” in British English, and a “flutist” in American English.

This type of flute is used in many ensembles, including concert bands, military bands, marching bands, orchestras, flute ensembles, and occasionally jazz combos and big bands. Other flutes in this family include the piccolo, the alto flute, and the bass flute. A large repertory of works has been composed for flute.

A transposing instrument is a musical instrument for which music notation is not written at concert pitch (concert pitch is the pitch on a non-transposing instrument such as the piano). 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♭ (i.e. B♭ at concert pitch), 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.

For some instruments, a written C sounds as a C but is in a different octave; these instruments are said to transpose "at the octave". Pitches on the double bass sound an octave lower than written, while those on the piccolo and celesta sound an octave higher, and those on the glockenspiel sound two octaves higher.

A multi-instrumentalist is a musician who plays two or more musical instruments, often but not exclusively at a professional level of proficiency.

Also known as doubling, the practice allows greater ensemble flexibility and more efficient employment of musicians, where a particular instrument may be employed only briefly or sporadically during a performance. Doubling is not uncommon in orchestra (e.g., flutists who double on piccolo) and jazz (saxophone/flute players); double bass players might also perform on electric bass. In music theatre, a pit orchestra's reed players might be required to perform on multiple instruments. Church piano players are often expected to play the church's pipe organ or Hammond organ as well.
