When the performance direction is "cantabile" one must supposedly play it in a song-like manner, but how do I implement it in my playing? Is it just the nature of the piece that will do the work or do I have to add something more to my playing?
Also, technically speaking how can an instrument imitate human voice? Since I'm learning the violin, what should I do in that context? Do I change something about my bowstrokes? Add a lot of vibrato? Play tempo rubato? Also, can I do anything the music sheet hasn't directed me to do? For example playing legato is indeed an important component of cantabile playing but I can't slur all the notes, only the ones that are specified by the slur marks. So, simply playing legato (which is already covered by the score) should not be the answer, unless the nature of the piece makes it cantabile and the musician need not add anything to it (which I don't think is the case)
