The player should always bear in mind that the longer reeds are in use the flatter they become. In cases where a reed is not very much out, it can be toned down by frequent playing, rather than by experimenting with it. When it is too strong and not too open in staples or blades it may be partly because it contains too much wood, a matter which can be easily rectified with fine sandpaper. A reed that is too strong owing to its being too open in the blades can be made considerably closer and easier to blow by taking a common cork, making a deep cut in the end of it, and inserting the blades of the reed into the cut, then tying a piece of cord round the cork sufficiently tight to close the blades, and leaving it in that position for a few days. The width of the staple should, however, be tested before this is done, as if it is too open making it closer by the process already explained will make the blades closer also, and save the trouble of using the cork. It should be noticed that when chanter reeds have certain false notes, such as a sharp high A or a flat high G or E, this is caused by the reeds being improperly fitted, the points of the blades being too thin or the sides of the reed being too thick. Care must therefore be taken, when fitting a reed, that all the different notes are true, after which it should never again be touched except when actually requiring attention. The beginner may find some difficulty in distinguishing the true sound when the chanter reed is in his mouth. He should therefore put it unto the pipe and sound it, when he will be better able to judge, as he will hear the sound from a greater distance. The chanter reed should always have a clear, distinct, shrill sound, accompanied with a full and firm tone in every note. V.—DRONE REEDS. The small drone reeds should sound smooth and firm, with a clear humming sound, and the big drone reed deep and bass, and strong enough to bear the pressure of wind required for the chanter reed. New reeds are often hard to “strike in,” and have a rough or sharp tone. This is owing to their newness and dryness, and goes away with playing. They are also frequently inclined to close or stop. This is caused by the steam of the breath swelling the wood, and causing it to fall into its natural set. In this case, the tongue of the reed should be raised as high as it will admit of without straining, and the centre pressed down. Should it after this become too rough or flat, it can be rectified by bringing the tuning string a little towards the point of the tongue. Should this make it too weak for the strength of the chanter reed, the best plan is to raise the tongue and put a hair (out of the head) between the tongue and body of the reed, and as far back as the tuning string will permit.
