SOPP455: I found a Facebook video of an organ student of yours playing the Dupont Meditation

This question was sent by Kiel, and he writes: Hi Vidas, I found a Facebook video of an organ student of yours playing the Dupont Meditation. I have two rhythm issues I’m wondering if you can help me with. One being the 5 against 4 sixteenth notes. This is when the melody is on the moves down to the great and are on off beats. The way I’m currently playing it is the f’s are together, g flat is two by itself, three four and five are with the remaining three sixteenth notes. Is that correct? The other spot being the six measures of two groups of three triplets against the four sixteenth notes. Would you be able to explain where the sixteenth notes fall against the two groups of three triplets? Thanks. -Kiel.
