I am practicing some short guitar etudes. Many of them have short repeated sections, which are identical and so sound rather boring (example: both first and second half are played twice in this Sor's etude).
What is the easiest way to play them differently?
I tried playing one repetition louder than the other - the result is one sounds normal, and the second uneven (bad skills; will improve).
I tried playing one repetition normal, and the other nearer to the bridge - but that's harder to play and I don't like the sound.
So what else can I change to make short repetitions sound more interesting?
