Without jazz, would "standards" be standards? Fact is, jazz musicians took-and continue to take-a body of music rooted in late 19th and early 20th century musical conventions and re-conceive, rejuvenate and adapt them to changing aesthetics.
I originally took this up in this post, showing how jazz made All The Things You Are a standard. I ran across an interesting website, www.jazzstandards.com, and I'm going to use the vast amount of data they've compiled about jazz standards to expand the concept.
According to that site, these are the top ten most recorded tunes in the jazz canon, along with the year of their composition. [Notice these are all 30's and 40's tunes. In fact, in the top 300, there are only a handful that were written after 1950-but that's another story]. To keep the length of the post down, I'll take the first five of these tunes and post the earliest recordings I can find in the original context and compare them with the earliest versions I can find in the jazz context.
1. 1930 Body and Soul
2. 1939 All the Things You Are
3. 1935 Summertime
4. 1944 Round Midnight
5. 1935 I Can't Get Started
6. 1937 My FunnyValentine
7. 1942 Lover Man
8. 1930 What Is This Thing Called Love
9. 1933 Yesterdays
10.1946 Stella By Starlight
Body and Soul, written by Johnny Green for Gertrude Lawrence, was recorded by Helen Morgan in the same year it was written. The vocal has a rubato, recitatif quality to it, with plenty of vibrato. It fits comfortably in the stylistic parameters of the era; post-parlor music, with a bit of art song harmony and the heightened emotion of European cabaret. Morgan does the verse (the first section of the song before the chorus), which most jazz versions don't include; unfortunate, from my perspective.
Louis Armstrong also recorded Body and Soul in 1930. Right away we have the parallel universe of jazz made manifest. The Armstrong version is clearly a dance record, with a steady swing rhythm section. He approaches the tune with some measure of emotional commitment, but he completely displaces the melody rhythmically and his rendition, both vocally and on his horn, opens onto a different world than that represented by Morgan's version.
