Ricardo has made a nice video demonstrating how he learns and practices a complex falseta (in this case, one by Tomatito)

I personally enjoyed it a lot and found it very helpful.

I like how he taps his foot every 2 beats and learns the segments of the falseta that way, counting in 2's. A lot of Tomatito's falsetas are felt in 2's.

To me, there are some falsetas that feel better in 3's, but tapping foot in 2's creates a better groove and forces a nice drive through the falseta and also makes the rhythm tighter.
