<Li> Tikkurilan Soittokunta, Vantaa, conducted by Kimmo Nurmi </Li> <P> A school band is a group of student musicians who rehearse and perform instrumental music together . A school band is usually under the direction of one or more conductors (band directors). A school band consists of woodwind instruments, brass instruments and percussion instruments, although upper level bands may also have string basses or bass guitar . </P> <P> Instrumentation for the wind band is not completely standardized; composers will frequently add or omit parts . Instruments and parts in parentheses are less common but still often used; due to the fact that some bands are missing these instruments, important lines for these instruments are often cued into other parts . </P> <Table> <Tr> <Td> <Dl> <Dt> Woodwind </Dt> <Dd> Piccolos 1 (, 2) </Dd> <Dd> Flutes 1, 2 (, 3) </Dd> <Dd> (Alto flute) </Dd> <Dd> Oboes 1 (, 2) </Dd> <Dd> (English horn) </Dd> <Dd> Bassoons 1 (, 2) </Dd> <Dd> (Contrabassoon) </Dd> </Dl> <Dl> <Dd> (Clarinet in E ♭) </Dd> <Dd> Clarinets in B ♭ 1, 2, 3 (, 4) </Dd> <Dd> (Alto clarinet) </Dd> <Dd> Bass clarinets 1 (, 2) </Dd> <Dd> (Contra - alto clarinet / Contrabass clarinet) </Dd> </Dl> <Dl> <Dd> (Soprano saxophone) </Dd> <Dd> Alto saxophones 1, 2 </Dd> <Dd> Tenor saxophone </Dd> <Dd> Baritone saxophone </Dd> <Dd> (Bass saxophone) </Dd> </Dl> <Dl> <Dt> Brass </Dt> <Dd> Trumpets / Cornets in B ♭ 1, 2, 3 (, 4, 5, 6) </Dd> <Dd> (Flugelhorns in B ♭) 1 (, 2) </Dd> <Dd> (Alto (tenor) horns in E ♭) 1, 2 (, 3, 4) </Dd> <Dd> Horns in F 1, 2 (, 3, 4) </Dd> <Dd> Tenor trombones 1, 2 (, 3) </Dd> <Dd> Bass trombone </Dd> <Dd> Euphoniums / Baritone horns 1 (, 2) </Dd> <Dd> Tubas </Dd> </Dl> <P> </P> </Td> <Td> <Dl> <Dt> Percussion </Dt> <Dd> <Ul> <Li> Non-pitched (possibilities): <Dl> <Dd> Snare drum </Dd> <Dd> Bass drum </Dd> <Dd> Tenor Drum </Dd> <Dd> Cymbals </Dd> <Dd> Tam - tam </Dd> <Dd> Triangle </Dd> <Dd> Tambourine </Dd> <Dd> Guiro </Dd> <Dd> Timbales </Dd> <Dd> Slide whistle </Dd> <Dd> Sleigh bells </Dd> <Dd> Wood blocks / Temple blocks </Dd> <Dd> Tom - toms </Dd> <Dd> Bongos </Dd> <Dd> Congas </Dd> <Dd> Claves </Dd> <Dd> Anvil </Dd> <Dd> Vibraslap </Dd> <Dd> Wind Chimes </Dd> <Dd> Rain Stick </Dd> <Dd> Whip </Dd> <Dd> Maracas </Dd> <Dd> Finger Cymbals </Dd> <Dd> Drum kit </Dd> </Dl> </Li> <Li> Pitched (possibilities): <Dl> <Dd> Timpani </Dd> <Dd> Glockenspiel </Dd> <Dd> Xylophone </Dd> <Dd> Marimba </Dd> <Dd> Crotales </Dd> <Dd> Vibraphone </Dd> <Dd> Chimes </Dd> </Dl> </Li> </Ul> </Dd> </Dl> <Dl> <Dt> Keyboards </Dt> <Dd> (Piano) </Dd> <Dd> (Celesta) </Dd> <Dd> (Organ) </Dd> <Dd> (Synthesizers) </Dd> </Dl> <Dl> <Dt> Strings </Dt> <Dd> (String bass) </Dd> <Dd> (Harp) </Dd> <Dd> (Electric guitar) </Dd> <Dd> (Acoustic guitar) </Dd> <Dd> (Electric bass guitar) </Dd> </Dl> </Td> </Tr> </Table>
