Look up the difference between a concert pitch note and the one produced the instrument in question to transpose it. Players who want to be able to transpose music written for one instrument to another must change the notes based on the pitch produced the original instruments. A C played on a B-flat clarinet, for example, will produce a B-flat note. The player must flatten each note two semitones to transpose a B-flat clarinet piece for an instrument like a guitar that plays notes at the written pitch.
Different instruments produce notes that are not at the same pitch as those written in the music notation. This is due to the fact that they do not always have the necessary notes to reproduce a song exactly as it was written. This category includes instruments like the alto flute, clarinet, saxophone, and trumpet. To play music written for one of these instruments at the correct pitch, the player must transpose the instruments according to how far they deviate from the written pitch.
On the internet, you can find a variety of lists of different instruments and their pitch differences from written notes. Anyone who wants to transpose instruments should look through these lists to find the instrument they want to use. The written note will be displayed first, followed the actual produced note. When transposing instruments, intervals can be used to describe the distance between the written note and the produced note. The original note is counted as the first in a “minor 3rd ascending” interval, which is two notes higher than the original note and flattened to make it minor.
When musicians transpose instruments, each note written down in the piece of music should be changed the same amount. If a note is designated as a C in a piece of music for the horn written in F, it will be played as an F. This is a perfect fifth below the written pitch, and it can be calculated counting five whole notes down from the original note, keeping in mind that the original note should be counted as one. If a different note appears in the same piece of music, it must be changed the same amount, for example, a D must become a G. This is accomplished counting down from one to five: D one, C two, B three, A four, and G five.
