4 drones (top pulls) and 4 stops (lower pulls) to direct the air over the upper or lower reeds. Fixed keyboard, integral bellows, and dozens of sound combinations. Finish color and decoration style may vary from photo. The Harmoniums are tuned to A = 440 (Hz) within 5-8 cents; rarely are they off by 10 cents. A cent is a unit of measuring intervals in music. Each half step (semitone) is made up of 100 cents. The 440 (Hz) represents the frequency of sound wave for the A note. If you double the frequency, you play the A an octave higher. Made in India.
