With music it is easy because the logical links and recollection is all there. It is true of smells sometimes but I can never figure out why a certain smell, sort of like molten tarmac reminds me of going to the local library when I was at nursery school. Or why certain books that have that distinctive smell, evoke an emotional feeling, but what I don’t actually know. Most bizarre.

Another very powerful way of calling up things from your memory I have found is smell. Like when I wake up early in the morning, go outside and smell fresh morning air with dew on the grass I am distinctly transported to then I used to go camping in France as a child with my family and getting out of the tent in the morning. Like you say with your music, almost as if you are actually standing there. The smell of a coal fire burning carried on the air transports me to North Wales and walking along the beach in Nefyn where such smells are commonplace in winter. There are others too but those are the most noticeable ones.
