I would advise to improve different types of playing tremolo, due to which you refine this technique. You can practice them in terms of playing any piece you choose. Slow tempo with articulate attack is obligatory. A metronome is a plus. You should play a piece wholly from the beginning to the end, while controlling dynamic evenness and note's value. While playing quintole tremolo (piami...), finger "i" always goes after finger "p". This disciplines right hand with no extra movements. www.classicsofsound.com www.dmitrinilov.com
