Hi Norm,
Probably all you need do is change over to a conical bore flute, such as a Dave Copley Delrin, or Rob Forbes Delrin flute, or maybe if you feel you the need for wood, a Burns folk flute here in the US. Or a new or used M&E or Seery flute in Polymer or Delrin (respectively) from Ireland, and you will be set to experience the next level of flute performance for ITM. The Dixon 3 piece polymer flutes or Bleazey wooden flutes (in the UK) will also give you the same change from the cylindrical bore Hammy flute you’ve been playing. There are others too, that I haven’t specifially mentioned, though from my experience and research, not many others are too noteworthy to bother with, unless you want to do your own legwork in testing them and see how they relate to your skills set.
Though, I will say that over a fair trial period, either the Hammy or Tipple flutes will give you much for your money, as your embouchure develops-you can make them sound great, as you put in the time to develop your skills. But if you are looking for an immediate change in tone, you will probably find it in a conical bored flute, which is the norm for most Irish traditional music being played today.
So, it’s really up to you, and where you want to go to be at your optimum level in a keyless flute. You will still have to put in the time to make any of them sound good to others. There’s more involved than just the basic tones that are the usual in ITM. Much more depends on your skill at playing the music, and the flute is not the deciding factor in tone or playability.
You could easily stay with your Hammy practice flute for a while, provided you are playing all you can, and developing your musical skills for the flute (breathing, timing and tune mastery-all technique that comes from you), so you will have to decide which you need to work on most for where you want to go.
If you need an easier or more comforable reach, then the conical bore flute will most likely give you that, but the rest depends on your embouchure and skills in playing the music. Do you need to “upgrade” your flute? That’s your call, but most likely, you just need time in to make the flute and music sound the way you want it to be. There is more in the details, than the flute, to sounding the proper way. Maybe a little easier on the conical bore flute, but not necessarily so. Upgrade when you feel limited in your music, and go from there. Just remember to have fun, as that is what music is all about, unless you’re looking to it as your profession. Then it’s much more than what you thought it to be, and you must set different requirements and goals to go along with that.
Otherwise, just have a blast!
