Some other quintets in classical music are the wind quintet, usually consisting of flute, oboe, clarinet, bassoon and horn; the brass quintet, consisting of two trumpets, one horn, a trombone and a tuba; and the reed quintet, consisting of an oboe, a soprano clarinet, a saxophone, a bass clarinet, and a bassoon.
Classical chamber ensembles of six (sextet), seven (septet), or eight musicians (octet) are fairly common; use of latinate terms for larger groups is rare, except for the nonet (nine musicians).
In orchestra, the concertmaster (principal first violin player) is the instrumentalist leader of the orchestra.
In orchestras, the individual sections also have leaders, typically called the "principal" of the section (e.g., the leader of the viola section is called the "principal viola").
A pops orchestra is an orchestra that mainly performs light classical music (often in abbreviated, simplified arrangements) and orchestral arrangements and medleys of popular jazz, music theater, or pop music songs.
A string orchestra has only string instruments, i.e., violins, violas, cellos and double basses.
In the string family, there are sections of violins (I and II), violas, cellos (often eight), and basses (often from six to eight).
The standard woodwind section consists of flutes (one doubling piccolo), oboes (one doubling English horn), soprano clarinets (one doubling bass clarinet), and bassoons (one doubling contrabassoon).In jazz ensembles or combos, the instruments typically include wind instruments (one or more saxophones, trumpets, etc.), one or two chordal "comping" instruments (electric guitar, piano, or Hammond organ), a bass instrument (bass guitar or double bass), and a drummer or percussionist.Jazz ensembles may be solely instrumental, or they may consist of a group of instruments accompanying one or more singers.A sinfonietta usually denotes a somewhat smaller orchestra (though still not a chamber orchestra).Larger orchestras are called symphony orchestras (see below) or philharmonic orchestras.Terms such as "piano quintet" or "clarinet quintet" frequently refer to a string quartet plus a fifth instrument.
