TUNING AND ADJUSTMENT l Pianos are delicate instruments which need professional attention periodically. Basically there are two types of professional piano care: tuning and adjustment. Tuning means correcting the pitch of every note by retightening the strings. Each piano string is normally stretched to a pressure of about 90 kilograms (1981/2pounds), but eventually it will stretch further with use and lose some of its tension, causing the piano to lose its correct pitch. The strings need to be tuned once or twice a year to restore them to their proper tension. Adjustment involves the entire piano action, keyboard and pedal movements. Proper adjustment is especially important for grand pianos. Whether the piano will perform properly or not depends on how accurately the adjustment is made. Tuning and adjustment should be done by an expert. When your piano requires either one, ask your Yamaha dealer or call a specialist. Your dealer can also advise you about the interval between adjustments for your piano under the circumstances in which it is used. STIMMEN UND NEUEINSTELLEN l Stimmen bedeutet, den Tonabstand berichtigen, indem man die Saiten nachzieht. Jede Pianosaite ist so gespannt, daß sie eine Belastung von etwa 90 kg aushalten kann. Selbst bei bester Pflege dehnen sich die Saiten und verlieren nach und nach etwas von ihrer Spannung, wodurch der Ton unrein wird. Unter normalen Umständen genügt ein zweimaliges Stimmen pro Jahr. Toulouse Lautrec AFINACION Y AJUSTE l Los pianos son instrumentos delicados que requieren atención professional periódicamente. Básicamente hay dos tipos de cuidado profesional para el piano: afinación y ajuste. Afinación significa corregir el diapasón de cada nota reajustando las cuerdas. Cada cuerda de piano es normalmente tensada a una presión de cerca de 90 kilos (1981/2 lbs), pero eventualmente la cuerda se estirará más con el uso perdiendo su correcto diapasón. Las cuerdas necesitan ser afinadas una ó dos veces al año para devolverles la tensión adecuada. l l 90 ÍËÎÓ„ 198-1/2 90 1-2 Yamaha ËÎË
