Those studying composing/arranging and listening in SQA Music exams pretty soon come upon variation form. If you’re lucky enough to have an iPhone or iPad you can download a free app containing a recording by Kimiko Ishizaka along with a score (with moving cursor) of one of the best sets of variations of all time, Bach’s Goldberg Variations.
You can get the iPhone app here http://www.opengoldbergvariations.org/soundsnips-free-iphone-app-featuring-open-goldberg-variations
and the iPad version here:
I’m not really sure what musical dreams are being sold in this video by John Q. Walker – particularly from 9′ 55” to 11′ 18” – but it’s certainly interesting. Without giving the game away, it sounds like a comprehensive, cross-referenced database of musical nuance and human emotion would be required. Perhaps it’s entirely natural to be incredulous of possibilities which lie far in advance of your own lifespan – although in this video interview he concurrs with the estimation of 10 -20 years.
However, there is some great footage of a young Glenn Gould playing some of Bach’s Goldberg Variations (his first of two recordings, separated by 26 years) and some lovely photographs.

This Youtube video shows the Aria and Variations 1 – 7 from the later recording of 1981. May I recommend the elegant, lyrical fireworks from 7′ 14” to 7′ 50”
