Etude No.9 (manuscript Version) by Villa-Lobos

This collection of etudes has an interesting twist or two in its history, which has only recently been unearthed. For decades this collection was listed as having been composed in 1929. The published edition and other circumstances surrounding the composition give no obvious clue concerning the existence of an earlier version. In 1996, however, it was revealed by Eduardo Fernandez in the magazine Guitar Review that another manuscript of these etudes was in existence, carrying the date of 1928. It turned out that this version had been filed away unnoticed for many years in the Villa-Lobos museum in Rio de Janeiro. The question several scholars have asked in recent times is whether the later version amounts to a revision by the composer, or is a touching-up by another hand.
