Rachmaninoff Preludes op. 23 1-5

Hello,

My new years project this year was to try to learn Rachmaninoff (beyond the much played C# minor prelude).

I can do play throughs from memory of 1 and 5 at this time. However I am really struggling with tension for #5. Is there a good video on Tonebase about how to avoid building tension in your arms with all the percussive 16th figurations at the end of each measure?

Thanks!
