Quick question about this piece: page 17 in my edition of the 30 etudes.. waltz in B minor. It starts as an andantino waltz then moves to 6/4 marked L'istesso tempo with quarter=eighth. okay then back to 3/4 but marked quarter=eighth which I assume is a misprint. then back to 6/4 with the quarter=eighth again... then ends in 3/4 which is marked eighth=quarter which I assume is correct. what exactly happens at the 6/4 sections? are my 1 and 2 and 3's suddenly 1 2 3 4 5 6's with a more singing phrasing (it's also marked cantando)? or do I hold steady on the count because of the L'istesso mark?
