Sorry, but I do not understand your question. Do you mean what is the difference between Gnossienne no. 1 and 3 because they are both marked 'lent'? If that is the case, the two main differences are that they are in different keys, and the melody is different. These are obvious things, though. Maybe you're asking about something else....
Thank you for your reply.
I was trying to say that Gnossienne No.1 and Gnossienne No.1 Lent by Lang Lang. if you go to iTunes store and look for Erik Satie Lang Lang and then you try the same but with Lent.
this is what i meant
