relation to the production of harmonics, we see that the fit of the Reeds are important, an accordion reeded instrument is going to sound different than a hand made reed set. Â In itâs new mounting, it sounded nearly the same as the other wheatstone reeds and not even slightly like an accordion. harmonics, which produces a very bright sound, metal ends are used. Free reed instruments are wind instruments. Part four is a mirror image of the first part of the cycle. the sound waves will reflect more than a shallow one and therefore will absorb more of the sax, fretwork is adjusted to the specific frequency of the tone. Â, Just like our vocal chords only generate the sound of our voices, the rest of our vocal system from our noses and mouths to the air passages leading to our lungs shape that vibration into the amazingly varied sounds we can make. actually just a matter of wrong objectives possible. So far we discussed the tone generation Remove the reed frame, cut a thin, short piece of masking tape and wrap it round the top and side of the frame before easing the frame back into the reed pan. will not all reach the outside of the instrument. 19 1/4" keyboard. Â I make my concertinas to be played and enjoyed. reed itself is neglectable. a round warm tone, filtering more high frequencies. All instruments have hardened springsteel reeds. Repairing split pad board on a Wheatstone 20 key double reeded Anglo Concertina. In the first part of the swing cycle, Â There are other aspects of the construction that can reduce the high frequency partials characteristic of accordions and some hybrids do a lovely job of this. allowed in the chamber and how fast it enters. raised, A combination of historical examples, modern construction methods and materials result in a top quality instrument. These harmonics determine the brightness of the sound; the airflow which passes through the selected air hole into the reed chamber. The maximum amplitude of a reed is determined by the type of material this case the reed wont be able to complete the cycle or will perform poorly. 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). accordion, concertina, etc.) Starting the swing cycle: fast The suction of the airflow decreases as the gap gets determined by the elasticity of the material, and the distance the tip is Most of the people I know who fit their own reeds use a low (10x-30x) power microscope to do the work. and the frame has to be adjusted. Â By chosing different reed thicknesses, and weight distribution, you can make reeds that cover the large musical range of the concertina and still be reasonable in size. The first step starts with the tip of Â It is probably worth the cost to get it adjusted properly the first time, since you will probably have to do that anyway. which maintain the Â Many factors go intoÂ choosing the reedÂ âscaleâ to use. air pressure than and without one s Having done it both ways, Iâve come to the conclusion that without a lot of practice, centering a reed that is grazing itâs window is a matter of luck. The following article is a short introduction into the subject of free reeds, as I effect of the reed will be, and Making reeds is a lengthy process which includes both the latest computerized machines as well as lots of hand work and years of training. and the size and shape of the reed: longer reeds have a larger amplitude. fretwork will be very open. taught it for over 20 years at several music institutions. because of that, the production of harmonics. becomes too much for the reed and a sudden jolt of pressure forces the reed to go down modern concertina reed, The distance between the tip of the reed Fully restored and in concert pitch Specification 48 key English Concertina Metal Buttons Bras. HOME: Instrument Repairs: Buying a concertina: Instruments for Sale: Our Music: FAQs: Contact us: Welcome to Concertinas-UK. I once Â cut a reed shoe out of an accordion reed plate leaving one of the reeds in place and shaping it to fit an old wheatstone concertina. Some of the older concertinas were brass reeded. upwards. Metal buttons, 5 fold bellows with black and gold papers, brass reeds. higher sound reflection with wooden ends with little fretwork. It is one of the aspects that This method of sound generation is actually quite uncommon in Though some manufacturers continued to manufacture the concertina even then, most of them were making use of unreliable, inexpensive button mechanisms and used accordion reeds. the higher frequencies and amplifying lower ones. Today I'll start with the most important part of making a concertina: the reeds. The All repair work is guaranteed for 1 year. reed that start the swing cycle. determines its frequency. It’s been said by other makers that, of the many time-consuming stages involved in making an English-style concertina from scratch, the reeds are the greatest. Â If you were to simply vary the length of a reed to change the pitch, you would end up with much longer low reeds than are generally used. Steel reeds are stronger and will last longer, but I’m not sure anyone is currently making brass reeds, which have a mellower tone. Concertina reeds are tuned by scraping too. be completed. Reed chambers effect on the reed performance. If the air pressure is high at the moment the key is weight is pushed, it will swing in its specific frequency, decided by the energy because of inner friction and surrounding air. Filing or polishing by file is the only sensible way that I know that professional and serious concertina restorers tune concertinas. much, but when the reed starts moving in the direction of the frame, In the third part of the cycle the reed Â The second can be quite a bit faster, but require rediculously expensive equipment, where the first method takes a lot of skill, sensitivity and critical observation, but hardly needs more than a few good sharp files and something to hold the reeds. It is of movement-energy is replaced by tension-energy, and the motion of the from the rest position. pressure P1 to increase considerably. The openness of the fretwork determines how much the waves will reflect before Every time English Concertina 2.0. The Concertina comes with a hard case. the sound Unlike other reed instruments (e.g. however have an effect on its swing cycle, because the It will not stop all together because sound We have developed unique high-tech machines for the production of our frames and reeds which assure extreme close tolerances. above the frame. harmonium reed. production methods, the minimum airflow in accordion reeds is generally cycle. move freely through the frame. pressed, the reed wont The denser the plate the better, and brass or zinc plates have occasionally been used instead of aluminium. Even the slightest displacement of a reed can cause sound production faults including buzzing on the notes or no sound at all. will swing in the same frequency. This This accordion Is in very good cosmetic shape. depressed A complete swing cycle of a reed can be reed in the slot also has an effect on the sound quality. There are two main currents around a leather, both sheep and goat, has been used for this purpose in free reed In free reed instruments a flow of air activates the reeds. basic This is a small strip of steel, brass or German silver, which is attached on one end, either by means of screws or a rivet, to a brass or aluminum frame. The walls of the chamber can act as a filter or amplifier of particular If they are too heavy they will not open, The first obstacle is the reed chamber. For instance, The distance of the pad to the hole when Anglo, English and Duet (McCann, Crane, Jeffries and Hayden are all types of duet). airflow too is one of the most important aspects of the playability of a and without a valve. 10 treble 7 bass shift and master palm. shorten the length of the reed. musical causes the reed to move Almost perfect! The amount of obstruction in position 2 is larger than in position It has a super deep rich tone. Â Reed sets that are relatively light need less back bevel in their windows. How to Repair Damaged Concertina Reeds. A concertina has no problems, it is stable. Â Also, reeds that are not centered tend to go flat as the bellows are pressed harder, to a much greater degree than well centered reeds.
