A key to following the polyphonic music of Bach is to be able to single out the individual voices. You will be very much helped by having a score at hand. In a fugue, the theme is presented in one voice, then repeated on the dominant with slightly modified intervals (but same rhythm and pitch profile) in another voice, then introduced in the tonic in a third voice and so on. A good pianist will bring out these entries, but seeing them in the score will most likely aid your understanding of what goes on.

Keeping track of modulations throughout a piece can be quite challenging even for experienced musicians, but in the score these different tonal regions can be easily identified.

By the way, I think the ideas about self reference and Gödel's incompleteness theorem are much harder to grasp for most readers of GEB, but still the book is just as enjoyable.

Learning the musical concepts in the book "Gödel, Escher, Bach"
When I pedal forcing a little with my right leg, the bike makes a noise that I don't know how to describe. I'll try to do it. It's like:


a short "ting"
a tiny bell
if a small rock hits the down tube


I don't know what is causing this noise, but I think that it could be any of this things:


pedal
crank arm/pedal connection
crankset


I think the material of all these things is alluminium.

I don't feel anything (like a bad shifted chain) when I hear the noise.

It happens when there is movement and when there is NO movement (I use the brake, so the bike doesn'e move, stand using all weight on right pedal, and it makes the noise)

The pedals could be in any position, It is not in a particular position. Just pressing the right pedal.

Has someone else has this "problem"? Any ideas of where this comes from?

Update:
Yesterday I took out the chain and stood on the right pedal, and made the noise. Then is not the chain, nor the transmission system.

I put oil in the pedal axis, but had no luck. Also tried to loose the pedal, but the juncture point is too tight, and I couldn't.

Today I will try to use oil in the bottom bracket.

Update: here is a link to info on the bike http://www.diamondback.com/2012-sorrento maybe it helps to know the model of all the components.
