Liszt Un Sospiro Timing

[aklvkk]

Hi,
I'm currently practicing Un sospiro by Liszt and was wondering about the timing of the notes.
 
(I uploaded the sheet music of the part I'm describing to be clear.)

When the piece starts 7 16th notes are  grouped together as ascending and another 7 are grouped together as descending in an arpeggio form. I just wanted to make sure that I'm reading it right, and timing it so that the 7 16th notes are worth 1 beat (1 quarter note). Also the timing is awfully tricky when trying to play the melody in octaves, and I was doing it by intuition but decided against it and wanted to try to calculate where each of the notes go. Do you guys have any tips for this section?

I used to have a wonderful piano teacher but I had to quit because of financial reasons, so I'm teaching myself for now. Sorry if I sound stupid for asking obvious questions :/

May I suggest concentrating on "fitting" the arpeggios to the melody, which should be in strict time. It's actually quite easy if you concentrate on the important notes.

did you ever find an answer to your question 'cause i had the same question too about where the octaves fall!

Hi , there is a way to practice this 3 vs 7 rhytm
first you have to be comfortable with the first bars where the melody is a single note , then practice the arpeggios alone with metronome at a slow tempo (tempo<60 qpm) until you play all the notes in equal timing.
then practice at the same tempo the melody line in octaves alone without the arpeggios and try to keep the hands motion as if you are really playing the arpeggios.
then play the arpeggios alone (always with metronome) and repeat many times but try to not think about what you are playing , then start playing the melody (the arpeggios are still playing)and focus totally on it . Repeat that until you get used to the rhytm.
I hope this helps
