Recorded on this Barbara Bonney album

The first three of these songs (to texts by Aaron Schaffer) were written when Copland was just 18, only three years into his musical education and prior to departing for Paris to study with Nadia Boulanger. However, none of the four songs were published until 1989.
The first,
Night is rather impressionistic; it shows a strong influence of Debussy. in fact all four songs are very much European in their sound. There is no detecting what Copland would soon become, but that is not to say that they sound immature. I'm no expert on piano, or vocal music, but if there are any weaknesses in the composition they're well disguised. To my ears Copland seems entirely confident even at this early stage. Prodigious indeed.
The final of the four songs,
Alone, written a whole four years later certainly seems more mature to me. Based on an Arabic text by J. Duncan, it certainly has the feeling of a nocturnal Arabesque.
I wish I could comment more on Copland's vocal writing. Vocal/piano music is a genre i've barely dipped my toes into so if there is anyone with experience who knows the songs and can provide some insight i'd love to hear.
So nothing especially profound here, but certainly delightful and enjoyable. I loved listening to Barbara Bonney I must say.
