Since temperature has an effect on the instrument’s pitch, blow some warm air through it to warm it up before tuning. The amount of tuning slide adjustment needed to get the horn in tune will vary between individuals so there is no standard rule to follow (however, at 68°F pulling the main tuning slide out about 0.6” should more or less tune the instrument to A=442Hz). Take notice that when temperatures are warmer, the main tuning slide should be pulled out a little more, while cooler temperatures will require that you push the slide in. Also, the position and angle of your right hand in the bell will have an influence on pitch as well. Single Horns Slide the main tuning slide in or out to tune the instrument. Double Horns 1. Use the main tuning slide to tune the Bb side. * Instruments with a Bb tuning slide should tune with the main tuning slide as well. 2. Use the F tuning slide to tune the F side of the instrument. 24 Tuning 3. Pull out each of the valve slides between 1/ 5-2/5 inch. When pulling out the slides, make sure that the lever corresponding to the slide is depressed. 4. When the hand stopping technique is used, the 4th valve on the YHR-332 lets you use regular fingerings in combination with this technique. Also, when setup as shown in the illustration below, it can be used in the same way as the 2nd valve, lowering the pitch a half-step. * What is Gestopft or hand stopping? This is a technique used on F Single or Double Horns(using F side) where the hand is placed further into the bell to raise the horn’s pitch by a half-step and change the tone of the instrument. But doing so requires the player to transpose the score down a half step to produce the correct pitch. The 4th valve on the YHR-322 compensates for the difference in pitch when using the hand stop technique, so you can read the score as is and still get the correct pitch. 25 Maintenance ¦ Caring for your instrument after playing To keep your instrument both looking and playing well, make sure you take proper care of it after you have finished playing. When caring for the instrument, place it on a table or, hold it securely in your hands, taking care not to drop it. . Valve Slide Maintenance 1. Remove the valve slides to remove any moisture. * Removing the valve slide without holding the corresponding lever down creates a drop in air pressure within the pipe, creating a suction that can result in poor rotor function or damage to the inside of the pipe. 2. If the instrument has a water key, remove moisture from the water key too. * The valve slides are made of brass or nickel silver, which are both excellent at resisting corrosion. However, corrosion may appear if moisture is left in the instrument for an extended period of time. Please use caution. . Body Maintenance Use a polishing cloth to gently wipe the instrument’s surface. If dirt or tarnish is obvious, the following products can be used. For lacquer finishes… Polishing cloth + lacquer polish For silver plate… Silver c...
