I am searching for what high D whistles have the highest volume in the low octave. A bandmember of Cormorant’s Fancy (We play alot of acoustic gigs and are a 7-piece band.) is playing Clarke whistles and doesn’t like her Susatos. However, the Clark whistles are now very loud when playing in the lower octave. I am aware of Susato and Silkstone, both of which are very loud whistles. What other whistles are you aware of that have a high volume in the low octave?
The closest I’ve found to the Susato in that regard (but with a much, MUCH better sound) is the Sweetheart “Professional” birch laminate whistle. I use mine to play for Morris Dancers, and it does very well. It’s a nice, responsive whistle too…I’m very fond of it.
It will also go up into the third octave, so if it works better for you volume-wise to start on high D, it’s doable.
Another high volume possibility is to order a Brassy Polly from Serpent - (not the current “Sweet Polly” - ask for the “Brassy Polly”).
It’s not the easiest whistle to play at first (it can accept a LOT more air than it needs - rather like a Clarke original) but it’s loud, in tune with itself, and tunable. Not to mention cheap - $25, last I looked.
Once you adjust your embouchure, it’s actually an easy player (predictable, responsive). It’s not always my first choice D whistle (I’m more likely to pick up my Sweet Polly or Syn) but when I’m in the mood for its volume, I can play it for hours without difficulty. Solid lower register (easily as loud as a Susato), but more balanced across its range (ie, much less loud than a Susato in the upper register).
Not to say anything against the other suggestions, but I’m pretty happy with mine.
