Hi, I studied these works in the 1980's, and have since largely forgot about them. Well imagine my delight when I discovered their copyright expiration! French publisher Max Eschig has largely ignored this work since first published in the 1950's. Though a reissue in 2006 fixed the wrong notes, many of the issues of modern engraving practice remain.
Heitor Villa-Lobos has been out of copyright in Canada for several years, but copyright remains in USA, EU etc... In order to fix a problem that has existed for at least 70 years, it has become apparent that a complete re engraving is necessary. Necessary but insufficient. A new engraving of the work will not guarantee an error free result. What is needed is a release of source files under a license that is Free enough to allow for modification. Something like Creative Commons 4.0? I started the project of re engraving the guitar works of Villa-Lobos in November 2024, and have just completed the Cinq Preludes. They are posted, along with lilypond source at https://imslp.org/wiki/Preludes%2C_W419_(Villa-Lobos%2C_Heitor) It is truly amazing the improvements that are possible with good tools, and a modern disposition. I have 2 movements of the 5 piece Suite Bresilienne finished, then on the Choro No 1, and the 12 Etudes. Of course anyone with sufficient skill, ambition, etc is welcome to help! How about the 12 Etudes? thoughts? -steve
