Orchestral tubular bells, tuned metal tubes struck with mallets — bright, penetrating timbre. Standard in film scores for magical, dreamlike moments.
You hear them in every second fantasy production: those bright, bell-like tones that cut through the mix like icicles. These are Deagan Bells – an orchestral glockenspiel consisting of tuned metal tubes struck with mallets. The instrument originates from the USA (invented by J.C. Deagan in the 1920s) and has become as established in film music as hardly any other percussion instrument.
The practical side: On set or in the scoring studio, your composer uses them to create moments that are not quite of this world – magic, dream sequences, magical transformations. The tubes are individually tuned (usually two or three octaves), and depending on which you strike, you produce a crystalline, almost supernatural timbre. The special thing: Unlike glockenspiels (Orff instruments), Deagan Bells have this penetrating brightness that cuts through any mix without being loud. A soft strike often has more intensity than a powerful one.
In the sound design context, we like to use Deagan Bells for transitions, for the auditory visualization of magic, or for subtle, subliminal signals. I remember a superhero production where we used stacked Deagan Bell motifs to mark the activation of superpowers – not with a dramatic hit, but with this elegant, almost immaterial sound. The stuff cuts through action scenes too, without seeming competitive.
Important for your work: The tubes resonate longer than some might think, so pay attention to sustain and decay – especially relevant when you layer multiple notes. The choice of mallets (plastic, felt, or wood mallets) also significantly changes the character. Soft mallets give you the dreamlike quality, hard mallets the sharper magical feel. In the film mix, Deagan Bells are often placed in the upper frequency range (3–8 kHz), where they are present without clashing with dialogue or strings.
