how did you create that high pitched "twee-te-te-te-te" melodic sound in that part of the ending starting at "it makes me weep, skip, sing it while I sleep"? it sounds like a pitched up keyboard but i can't be sure. it's very fanciful and cool sounding though
it's just a keyboard sound that's fairly dull and gets out of the way quickly. the entire rhythm of the sound is me actually playing all those notes in real time. use 2 or 3 fingers on the same note. if it helps, you can slow the tempo down to record it but i don't do that. it's more important how it's played than what sound it is. i know this because i used to do this all the time on a different sound that i no longer have access to, and i just recently started doing it again and i was very quickly able to find a sound that works fine for that. just has to be slightly dull and get out of the way quickly (short release). and the rest is all in the performance
