I have a Kobliczek renaissance tenor, which I have had for several months now and I regard it as well played in. I find that the very lowest notes tend to break very easily into the higher octave, and that throughout its range it tends to be sharp. Both problems are very substantially reduced if I keep breath pressure quite low – lower than I would normally use. Is this normal for the style of instrument? All the other recorders I have are baroque style, so I have no way of knowing to what extent this is normal, and to what extent it’s a quirk of this particular instrument.
