Hey, I asked the question about that 5,5,6 triplet thing! So, the song is in 4/4 time (slower tempo, about 80bpm). The full measure is a dotted eighth, then a sixteenth note tied to a quarter note, then that 5,5,6, triplet thing. So that 5,5,6 triplet should take up 2 beats. So, it's like dividing 2 beats into 3 equal parts (3:2 quarter note triplet), then taking those 3 equal parts and dividing them again into 5,5, and 6 respectively?
so basically if you just played this as 32nd notes, no one would ever know the difference. we're talking about squeezing 16 notes into 2 beats at 80bpm. grouping it evenly in thirds as 5+5+6 is not really going to be distinguishible from even 16, from the listener's or player's perspective. i would ask the composer what the point was of writing it that way, and maybe they could give you some insight as to how it's played. sometimes composers like to showoff on the page how many crazy looking numbers they can put in, now i'm not suggesting that this composer would do such a thing! but it's worth a thought
