Panknos, yes the youtube "video" contains only audio. If its not working for you, you can listen to an excerpt here (along with excerpts from the entire rest of the album): https://www.allmusic.com/album/virtuoso ... 0001939611
There are multiple other uploads of this on the internet. If you simply search for "Honti Larghetto" you'll come up with several. Looks like the rights to Honti's original recording got sold off and this particular track has made it to a number of other guitar compilations.
Stephen, I've come to the same conclusion. Despite the attribution the piece is not by Tarrega.
But who wrote it? Is it even a classical piece at all? Or is it some more recent classical-like piece that Rita Honti wrote herself or appropriated for her album? FWIW, this track was recorded in 1992, and there are three other legitimate Tarrega pieces on it, Capricho Arabe, Lagrima, and Adelita. Honti is a serious classical player, I'm sure she knows the difference. If I knew how to get in touch with her, I'd ask her directly.
As to difficulty, I'm sure there are easier tremolo pieces. . .and in fact I've already learned Carcassi Op 60 #7, which could be considered a "tremolo" piece, although I don't think of it as one. I consider this to be "easy" not because of its technical difficulty (the tremolo part probably isn't any easier or harder than any other), but mostly because I like it and its pretty short, I don't think it would take too long to learn.
If I can find the answer I'll post it.
