"Of course the most difficult thing on the violin is always intonation. The second one is rhythm. If you play in tune, in time with a good sound that's already high level. Those three are the main things"

Ruggiero Ricci, a distinguished violinist, is stressing the value of intonation, rhythm, and sound when playing the violin. Intonation, or the accuracy of pitch, is the most hard aspect of playing the violin. Rhythm is the 2nd most tough element. Ricci is suggesting that if a violinist can play in tune, in time, and with a great noise, they are currently playing at a high level. This indicates that mastering modulation and rhythm are vital for a violinist to reach a high level of playing. Ricci is emphasizing the value of these 3 elements of playing the violin, as they are the main elements of playing the instrument. He is recommending that if a violinist can master intonation, rhythm, and noise, they will have the ability to reach a high level of playing.
