Actually I found it. It's Green Onions by Booker T. & The MG's, it turns out. Perhaps symphony is the wrong term, but I meant a piece of music without onion. Thanks everyone!
Yeah.
That is a classic piece of soul music by one of the session bands (Booker T. and the "Memphis Group"- or "MGs") that worked for the Stax Volt label in the Sixties (southern soul that competed with Detroit based Motown). And was a hit in Sixties. And it has no vocals, and no lyrics. But its a normal 3.5 minute pop song.
And it IS blues based.
A pop (or soul or rock or country) song without words should be called "an instrumental". Not a "symphony" (symphonies are played by whole orchestras, and usually have several movements and can be as long as a whole album).
