J S Bach wrote his “Inventions and Sinfonias” as musical exercises for his pupils.They are a collection 30 short keyboard pieces, 15 in two part writing and 15 in three part.They are more commonly known as the two part and three part inventions. The two groups of pieces are both arranged in order of ascending key, each group covering eight major and seven minor keys. The inventions lend themselves to duet transcriptions and I have done so for a number of them using a duo of 2 flutes. I have taken some liberties with the notes in the 2nd flute part to avoid any "clash" with the upper part. I have also transposed the flute parts so they are playing within a comfortable range. Number 1 is now in G major, rather than C major, and the inventions all retain their relationship with this key: so no 15 is now in F sharp minor rather than B minor. They are all excellent exercises in playing scales/arpeggios in their varying keys.Individual inventions are also available. See related scores for details. Numbers included 1,3,4,5,6,11 & 15.
