I'd like for you to compare two different performances of Franz Liszt's 1881 "Trübe Wolken" ["Grey Clouds"], S.199--one by Leslie Howard, the other by Dominic Harlan.  To do so, please consult the score, the recordings, and their respective spectrographs.

For class, please write a paragraph or two outlining what insights about the piece and the performances you can glean from these documents. How do the interpretations differ?  Is one more appropriate to the composer's notation or to the title of the work?  Can you connect what you're hearing in the recording to the details on the spectrograph?
