So here is a website, for people who not only want to learn the songs but also gain a good understanding of them.
In the website you'll find for each song the lyrics, both in Yiddish and in latin transcription, French and English translations, all the song's vocabulary, links to listen to the song or get more information about it, and sometimes the melody transcription with a corresponding midi file. Sometimes also, a few words about the song's story or other details.
There are also on the website biographical notices for authors and composers, in French, with links to more detailed informations, most of the time in English. Also, a whole page of links about Yiddish and, of course, the glossary, with all the words in the songs.
We welcome all your suggestions, remarks, corrections, and we will heed them as far as possible.
