Very beautiful piece. In measure 17, are these triplets? If so why there is a triplet followed by a 2 sixteenth note in the second beat. The tempo is too fast for my ear to tell if I am hearing triplets or just sixteenth notes. I know I need to train my ear more 🙂
No, those are not triplets; you will see that if you count the number of notes in the measure. KP has made a mistake in notation. The standard rule of notation in an instance such as this is that the "beaming" of the sixteenth-notes has to correspond to the beats represented by the time signature. Therefore, each beat has to be "beamed" as four sixteenths. If KP wants the execution to show groups of three without changing the timing, then phrase marks have to be used over each three-note group, but the "beaming" must remain to show four sixteenth-notes per beat.
Measure 18 is a further instance of mistaken "vocabulary" three sixteenth-notes, three sixteenth-notes, two sixteenth-notes and then two groups of four sixteenth-notes each. Only the last two groups of four sixteenth-notes are correctly notated. The entire measure should be written as four groups of four sixteenth-notes per group.
Similarly, the left hand should not show two groups of eight sixteenth-notes as seen in some measures but, rather, four groups of four sixteenth-notes each.
KP should go through the score and make the necessary corrections.
