Hi there! The standard orchestration for She Loves Me features two options for your reed section. Either you have 2 reed instrumentalists ("2 Reed Version") and the doublings as listed, or 3 reed instrumentalists ("3 Reed Version") and the doublings as listed. 

For example - if you have two reed players you would use the 2 REED VERSION, and your first reed player (REED 1) would play the Alto Flute, the Bb Clarinet, Flute, and Piccolo.

If you have 3 reed players you would use the 3 REED VERSION, your third reed player (REED 3) would play the Bb Clarinet, Bass Clarinet, Bassoon, and Flute.

Hope this helps!
