How to distinguish the saxophone？
1. Appearance and workmanship
First, check whether the tube body has any artificial damage such as bumps, scratches, cracks, etc., and whether the joints are firm; whether the keys are bent and deformed under normal pressure; Is the gap between the link rod and the link rod too large, otherwise the keys cannot close the sound hole accurately, and whether the pad marks are accurate; the distance between the keys and the pitch should be consistent, and then, flick the link rod and button to judge the degree of flexibility .
2. Complete parts
A complete set of saxophone consists of these main parts: main body, neck, mouthpiece, reed, reed card, clip cap, sling, other (instrument case, cleaning cloth, cork oil, gloves).
3. Buttons and leather pads
There are many buttons on the saxophone, and there are leather pads on them. If the sealing is not tight, it will lead to no pronunciation or poor pronunciation. When checking, lightly press the pads to observe whether there is any gap, and then lightly blow each sound to check whether there is any leakage. Depending on the gas situation, pay attention to whether the volume and timbre of each tone are unified.
4. The strength of the spring
The uniform spring force on each key not only provides the player with a comfortable and consistent feel, but also determines the speed of the performance. If the spring tension is small, the keys will rise and fall slowly. Otherwise, the fingers will exert too much force, resulting in stiff movements and affecting the performance. Therefore, it is particularly important to require that each spring should have the same tension.
5. Accurate pitch
As mentioned above, the distance between the key and the pitch should be consistent, because it not only changes the sound quality and timbre, but also directly affects the accuracy of the interval. If a key is lifted too high, the pitch is high and the pronunciation is rough; If it is low, the sound is low and the pronunciation is dull, so it is difficult to guarantee the consistency of such instruments. Therefore, when purchasing, it is necessary to test the sound from the bottom to the top with a durable heart, and do not ignore this link. It should be pointed out that if there is a slight difference in pitch or timbre, it can be solved by controlling the mouth shape and debugging the instrument, but the first purchaser should carefully identify and consider it carefully. Reluctantly “make do” will inevitably affect the performance effect and hinder professional skills. improve.
