Hi Steffen,
Thank you very much for your considerations. I think to understand that Ligeti wanted the most transparent and delicate sound at the beginning of Atmosphères, so he asked for a combination of all the techniques allowing for it (sordino, sul tasto, dolcissimo, pp going to al niente). I believe using the sul tasto articulation contained in Solo Strings I, and keeping the dynamics a bit softer, can be enough to achieve that effect. I was thinking to add the filter included in VI, but the only thing that it seems to do is to cut the higher frequencies, and as you suggest it is not the expected result.
As for copyrights, this is something I’ve been asking myself often, and maybe you can help me on this matter. Can, presenting a virtual rendition of a copyrighted work in a forum, be considered copyright infringement, as if you were playing it in a theatre?
In the USA, the Copyright Act allows “fair use” of a copyrighted work “for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use, scholarship, or research)”.
In my country (Italy), the current law (dated 1993, but based on a law of 1941), allows for free use of a copyrighted work for “teaching, studying or researching, including practicing and essays of amateur level music activities” (my translation), and in general in any case of non-profit use.
Still in my country, based on my experience as an amateur musician and a theatre manager, I guess this type of activity would not be approved by the national copyright agency (SIAE), usually acting according to their own rules, notwithstanding the law. For example, playing Schubert would still be only possible after their authorization, and paying the rights (formally, to the editors of the used score).
I wonder how this works in Austria, whose laws should be the ones to be considered when posting something in this forum. I’m personally ready to retire any example might I post, in case the owners of the rights ask for it. I would also comply with the law, in the hope that the “fair use” mentioned above is a common rule.
Cheers,
Paolo
