I’m so excited! Today, I bought I Sweetheart D fife in cherry today at a local traditional music shoppe. I absolutely love it! It’s very responsive, and I’m enjoying every minute of it! I tried out the cherry fife and the walnut fife (I’m pretty sure it was walnut), and I decided the cherry was more my style. I also got the music book “The Fifer’s Delight.” That book has some awesome songs that are a blast to play.

There’s also a new ‘diamond wood’ Sweetheart D fife,
made of laminated birch. Quite good sound.
I did play the Laminante one once and it was really cool.
I purchased one of his D fifes made of fruit wood in 1994 (House of Musical Traditions on Tacoma WA. D.C.?). It has survived a lot of misuse over the years with no cracks and little maintenance. The highest note that I was ever able to play consistently and well was the third octave E. That may be my embouchure. It seems (to me) a very soft sounding instrument. I find that the embouchure allows great flexibility with pitch allowing you to hit an F nat, however it also allows you to play it way out of pitch.
I do wonder if his instruments have changed much in the last ten years.
The nice thing about it is that you can play along with whistle tutors and be playing at the same octave.
