I don't know how old-fashioned these pieces are now considered to be. I suspect they are either loved or hated by most people. I got the Liebesleid from a charity shop, and I decided to get the rest off IMSLP. (see attachments).

I'm reading Yehudi Menuhin's autobiog., and he rather astutely, to paraphrase him severely, says that Heifetz was tangible, but Kreisler was intangible.

Little German lesson for you (because the two words are so often confused):

Lied (rhymes with feet) is a song. Plural Lieder, rhymes with feeder.

Leid (rhymes with fight) means suffering, and the piece is called Liebesleid, love's suffering, not Liebeslied, lovesong. (I'm not sure Leid has a plural. In the case of Goethe's Die Leiden des Jungen Werthers, Leiden is the plural of Leiden, slightly different).

Freud is an abbreviation of Freude, which means joy. (hence Ode an die Freude)

Schön Rosmarin means "beautiful rosemary". I guess Kreisler liked roast lamb.

No, they are not for beginners, but I thought I'd collect them together so I had the set.
