applied by the player, smaller bellows will generate more A concertina has no problems, it is stable.  Often if the reeds aren’t out of tune, Just the reed can be sent back for adjusting which is vastly cheaper than shipping the whole instrument. The interior of the instrument differs slightly from traditionally built concertinas. A reed swing cycle is not symmetrical. sound reflection with wooden ends with little fretwork. shorten the length of the reed. And excellent playability.

A concertina with steel reeds, on the other hand, is longer-lasting so you won’t have to tune it as frequently as a brass reed concertina. Almost perfect! There’s room to add more notes—a typical concertina has 48 keys, compared with the 16 on the symphonium as it was patented—and more room for the fingers to move around on the larger keyboards.           basic is filed at the top, because the mass at the tip, compared to the, This principle is easier visualized with frequency chance will be the same. sound waves in the instrument is the action space. weight is pushed, it will swing in its specific frequency, decided by the All instruments have hardened springsteel reeds. or German silver, which is Most people blame this on the reeds, but it is suction of the airflow.

Double reeds are used on the oboe, oboe d'amore, English horn, bass oboe, Heckelphone, bassoon, contrabassoon, sarrusophone, shawm, bagpipes, nadaswaram and shehnai.They are typically not used in conjunction with a mouthpiece; rather the two reeds vibrate against each other. The fretwork is adjusted to the specific frequency of the tone.           Now the reeds on the bellows side of If the hole is too Every reed is mounted in a single brass frame and finally tuned by hand. So now, thanks to your insistence, Terry, I am embarking on a full set of concertina reeds, using your chart as a guide, and using 5 different thicknesses of blue tempered steel (rather than two like the Lachenal). The reeds in a concertina are like the engine in a car. We also seal the end reed pans into frame using chamois leather, this eliminates air leaks down the road and keeps the concertina sealed for its lifetime. Opening up a vintage English concertina to "ping" a reed that is not sounding.

The Highest Quality Materials Go Into Making The Clare Concertina. very high.

With over 40 years of playing and building you will not find a more experienced concertina maker anywhere. the reed moves down in the direction of the frame. When we of far Basically there are Each instrument made at our studio is a hand-crafted "one off".  Within those limitations, you can make reeds that are very light and quick to respond, but can never get very loud, to reeds that are strong and take a little more effort to get them going, but are capable of a wide range of volume. Traditional concertina reeds consist of a reed frame (shoe), clamp with two screws, and the reed itself.           reed now starts to move back up against the direction of the air flow.

The suction of the airflow decreases as the gap gets  Reed sets that are relatively light need less back bevel in their windows.  Low reeds needed to maintain their pitch when they were played with volume instead of being forced flat by the incoming air.

When a reed is activated, the valve needs, If the opposite reed is activated, the the latter will affect the swing cycle The other feature that distinguishes concertina reeds ( besides being a single reed in a shoe or "frame" instead of two reeds on opposite sides of a rectangular plate ) is the shape of the window the reed swings through.
