Volgadon - if someone, as I do, plays just the tune/top-line melody on a piano/keys set on "piano", it may be said that they are not playing it properly/not making proper use of the instrument's full capabilities OR that they are playing it in a folkie way. I like hearing just the tune on a piano, concertina, etc...maybe that's because I'm a folkie at heart.
WR AND FT - there are different kinds of sonnets (2, from memory, in my collection). And poetry, as with music, IS subjective - some HAVE happened to like at least some of mine, which do include some POETIC LICENCE.
