Greet your guests with pure music and always know when someone is coming or going with Jacob's Musical Door Chimes. Musical instrument maker Jacob Sokoloff takes great care in the tuning of this chime. The blending of its four notes, all tuned in the pentatonic scale, creates a pleasant and musical effect at the slightest movement of the door. Simply hang on the door knob and open the door to music! Corrugated display also available (free with 18 piece order).
