Ooh, some very nice ideas 😃

What a beautiful looking collection - a work of art in appearance, before you even get to the content!

Great choices (though must admit I need to look up the Pejačević and the Lindberg).
Mine would include the Bruch for violin & viola; and couldn't live without the Beethoven violin.

Oh please don't say Brahms is only for Autumn - many of us would have to hibernate through winter, spring and summer!
