Q: What do the colors in the bar-graph score mean? A: Each color corresponds to one line in the orchestral score, and therefore to an instrument or group of instruments; here's the key: http://www.musanim.com/pdf/MozartK550... I changed the color of the bassoon a little (so as to not be so close to the color of the "dissonance blast" effect).
Q: Where can I get this recording? A: You can get the recording this video was based on (performed 2010aug15 by Das Orchester Tsumugi Science Hall in Fukuoka, Japan) at IMSLP ... http://imslp.org/wiki/Symphony_No.40_...) ... however, it's not exactly the same as what's in this video; there were quite a few wrong notes in the original recording, and I edited the audio to make the errors less noticeable.
