WANTED: Herman Klein Phono-Vocal Method

[Titta Ruffo]

Hello Gentlemen,

I am searching for a Phono-Vocal Method by Herman Klein. In 1909 he published 20 lessons for each voice type.

I am wondering if anyone ever encountered these discs. Let me know if you heard anything.

Thanks.

I never heard or seen one of these.

Here's a youtube of one ...

Thanks.

Yes, there is available 20 lessons for a contralto, and 3 for the soprano voice in youtube.

The rest (baritone, tenor, bass) and the remaining 17 lessons for the soprano is a mystery.

I'd like to know if these remaining discs exists, or if they were actually ever recorded.
