OK, before you start picking on me because Heart and Soul isn’t really a fiddle tune, know this: Fiddle Tune a Day is my game and I get to make up the rules. 
And, for the purposes of this game, Heart and Soul counts.
Moving on. I had a great time down at the Avaiya Studios in Boulder, CO working on a couple of soon to be released films, The Gratitude Effect, and Power of the Portrait. While I was there, I got to meet the lovely Jean Trebek, wife of Alex Trebek. As you probably know, I like to have other people join me on Fiddle Tune a Day from time to time, and when you get an opportunity to have Jean Trebek on Fiddle Tune a Day, you don’t pass it up, and Heart and Soul was one of the only tunes she knows on piano.
We had a great time goofing off. I think you will enjoy it too.
Heart and Soul (1938 song) From Wikipedia, the free encyclopedia
“Heart and Soul” is a popular song, with music by Hoagy Carmichael and lyrics by Frank Loesser, published in 1938. The original 1938 version was performed by Larry Clinton & his Orchestra featuring Bea Wain. The song’s A-section is often simplified as a repeating I-vi-IV-V progression and taught to beginning piano students as an easy two-hand duet ( example (help·info)). Much like the song “Chopsticks,” this (somewhat inaccurate) version became widely-known, even to those who have never studied piano. The chord progression, often referred to as the “’50s progression,” later became very common in the doo-wop hits of the 1950s and 1960s.
In 1939, three versions charted: Larry Clinton (reaching #1 on the chart), Eddy Duchin (reaching #12), and Al Donahue (reaching #16). The song later charted as #11 in 1952 by The Four Aces, as #57 in 1956 by Larry Maddox, as #18 in 1961 by The Cleftones, and as #25 in 1961 by Jan and Dean. Many other versions have been recorded.
I dodn't know what makes a fiddle tune, but I thought that was just fine! Thank you.
Don't you turn those pegs on the handle?
