For this piece, I use note pitches and overall song structure as palindromes. I did not attempt to reverse audio or audio effects, so if the audio were played in reverse it would not sound identical, although the pitches would be the same forwards and backwards.
Every instrument is played as a palindrome in some form. Short phrases, such as the violin melody and drum part, are stand-alone palindromes lasting a few measures long. The melody repeats in different chords, with the chord structure being a palindrome. The longer xylophone phrases are part of one large palindrome that lasts the entire duration of the piece. It reverses at the midpoint of the composition.
I consider this piece unfinished. I intended to do more but ran out of time. I think it needs a bass line, some more variability while still fitting within the palindrome structure, and perhaps different instrumentation.
