Instruments include: solo violin, 2 flutes, a 'ripeno' section consisting of 2 violins and a viola, a 'string' sections conisisting of a cello and double bass, and a harpsichord
Violin has the main melodic line but the 2 flutes are just as important
There are demanding techniques for the violin. For example, a 3 octave span, rapid demisemiquaver passage and double and triple stopping
There are constrasts of the solo violin entering after a tutti section b.1-3
The harmonic rhythm of the strings, and sometimes the flutes, are slowed down to make the monophonic solo violin more obvious
Flutes moves in 3rds and 6ths
Tutti sections emphasise cadences
The insturments are used to increased momentum through hemiolas
