Busoni – 25 original pieces and 15 Bach transcriptions

The Italian pianist Busoni’s important achievements as a composer were long over-shadowed by the fact that he was generally thought the greatest piano virtuoso after Liszt. The solo piano versions of Bach’s Toccata and Fugue in D Minor (for organ) and the Chaconne from the second Violin Partita are among his most well-known transcriptions. Read more >>

Hello, I've come across this question and I'm a little puzzled about the last bar. The question was to change the time from compound to simple time without changing the rhythm. I'm a bit stumped as to why the minims haven't changed to crochets and why the crotchets didn't change to minims!!

Any words of wisdom on this would be greatly appreciated!!

To convert a/b time to c/d time you take each note (x) and the new note (y) is :

y = (c/a) * (b/d) * x

So in this case

y = 3/9 * 4/2 x
   = 1/3 * 2 * x
   = 2/3x

So, a dotted mimim changes to a minim.
