The sopranino has the same range as the flute. Sopraninos are said to be pichy whiny and shrill. I even heard the term tin whistle used. Yet flutes and Eb clarinets solo all the time. I think w/ sopraninos we are in a catch 22. To get a good one lots of $$$$ has to be spent. Most people buy them as a occaonsonal 5th sax and get a bargain one. This is where the problems start. To get a decent nino you must spend some $$$$. They are not forgiving like the bigger saxes. Someday I would like to try the Yanagisawa nino. I'm sure it is great. I went overboard(mid life crisis{turning 40}plus the death of my Dad in April made me want to try a nino while I am relatively young rather than put it off til later years) w/ the R&C nino to get the high F and F# and the big bore warmth. Kinda like going from a Yanagisawa T-901 to a Selmer reference 54/36 tenor. T-901s are great saxes and the selmer refs take up a notch. I took it up a notch w/ my nino. I'll let you all know how it works out!!!
