TRANSPOSITION Advanced
Concert Pitch
Instruments like the violin, flute and cello, although reading in different clefs, all play at Concert Pitch. This means that the music on the stave sounds the same pitch when it is played. Here’s a list of instruments that read in concert pitch:
Instrument Key Clef
Violin Concert Pitch Treble
Viola Concert Pitch Alto/Treble
Cello Concert Pitch Bass
Harp Concert Pitch Grand Staff ----- Flute Concert Pitch Treble
Oboe Concert Pitch Treble
Bassoon Concert Pitch Bass/Tenor ----- Trombone* Concert Pitch Bass/Tenor
Bass Trombone Concert Pitch Bass
Tuba** Concert Pitch Bass ----- Marimba Concert Pitch Treble
Vibraphone Concert Pitch Treble
Timpani Concert Pitch Bass ----- Piano Concert Pitch Grand Staff
Organ Concert Pitch Grand Staff
Harpsichord Concert Pitch Grand Staff
*Trombones are keyed in Bb but the player still thinks in concert pitch. That means that when they play a C it sounds a C. **Tubas also come in different keys (Eb, F and Bb) but they always read the notes as written and change the fingering accordingly.
Transposing Instruments
Other instruments are called “transposing instruments” - when these instruments are played, they sound at a different pitch than what is written.
Some transposing instruments are still in the key of C but sound an octave higher or lower and some are different keys all together (eg: Bb, Eb, F)
Here’s a list of transposing instruments:
Instrument Key Clef
Double Bass Sounds 8ve lower than written Bass Guitar Sounds 8ve lower than written Treble ------Piccolo Sounds 8ve higher than written Treble Alto Flute (in G) Sounds Perfect 4th lower than written Treble
Cor Anglais (in F) Sounds Perfect 5th lower than written Treble
Clarinet in Bb Sounds major 2nd lower than written Treble
Clarinet in A Sounds minor 3rd lower than written Treble
Clarinet in Eb Sounds minor 3rd higher than written Treble
Bass Clarinet in Bb Sounds major 9th lower than written Treble
Contrabassoon Sounds 8ve lower than written Bass Soprano Sax (in Bb) Sounds major 2nd lower than written Treble
Alto Sax (in Eb) Sounds major 6th lower than written Treble
Tenor Sax (in Bb) Sounds 8ve + major 2nd lower than written Treble
Baritone Sax (in Eb) Sounds 8ve + major 6th lower than written Treble ----- French Horn Sounds perfect 5th lower than written Treble
Trumpet in Bb Sounds major 2nd lower than written Treble ----- Glockenspiel Sounds two 8ves higher than written Treble
Xylophone Sounds 8ve higher than written Treble ----- Celesta Sounds 8ve higher than written Grand Staff
Transposing on sight
Transposing instruments sometimes have to transpose on sight. If they are given music that is written in concert pitch, it is important to know which way you have to transpose.
The chart below shows which note each instrument has to play if they are reading in concert pitch. For example, a clarinet in Bb sees a written in C in concert pitch and plays a D.
Well Done!
That’s advanced transposition - you’re good to go!
