So, the thought just crossed my mind of composing a Tarantella. But the thing is, I have only listened to and played a few of them in my 10 years of piano playing, so I don't know much about what is typical. However I do know this. It is a dance from southern Italy that is typically in 6/8 but sometimes in 12/8 or 4/4. And it has a typical rhythm, namely this rhythm:
Tarantella rhythm
And the tempo is typically very fast, easily Presto. And the pieces themselves are typically short, not much longer than 5 minutes on the outside. And from what I know of the tarantella pieces I have listened to in the past and the ones I am listening to now, the bass is usually constant eighth notes or changes between eighths and dotted quarters whereas the melody has the typical 1 - a 2 - a, 1 & a 2 & a, rhythm(hyphens I'm using to represent that the note takes up 2 eighth notes) and the overall piece has a constant eighth note momentum until the final cadence.
Do I need to know anything besides the typical rhythms of the dance and the tempo and time signature it is in before I compose a Tarantella myself? Just asking because I have never written an Italian dance before. I've written French dances(the Minuet originated from France), I've written Austrian dances(the waltz has Austrian origins), I've even written Polish dances, but never an Italian one.
