Vittorio Monti (1868-1922) is an Italian composer, whose Cardas (1904) is a well known piece based on Hungarian csardas, traditional folk dance which starts slowly and ends in a very fast tempo written in 4/4 or 2/4.
Question from my student:
Does the 4th finger need to be curved when one plays the harmonics?
My answer:
It is very interesting and good question!
When one is playing the harmonics, we use the pad of the finger, not the tip, so naturally the 4th finger becomes very straight.
