Having been a professional flamenco dancer I teach Sevillanas on demand.
Sevillanas consists of four verses – in total only around 5 minutes – but there are quite a few steps and hand movements to take into account.
I would recommend at least 10 times/hours to reach a basic level.
We can add castanets and shawl if time permits.
