Musical Clocks

Verified

Clocks that play a tune, chime sequence or air on bells, a comb (as in a musical box mechanism), or organ-type pipes, at the hour or on demand, as distinct from automaton clocks whose principal feature is moving figures rather than sound.

Movement & mechanism

  • A separate musical train, commonly driven by a pinned barrel that lifts hammers to strike a nest of bells or, in later work, plucks a tuned steel comb
  • Release governed by the going train at set intervals (commonly the hour, or hour and quarter), or by a manual trigger
  • Some fine longcase and bracket clocks combine full Westminster- or Whittington-type quarter chimes on eight or more bells with an hour strike

Identification

  • A nest of bells, gongs or a tuned steel comb visible or audible in addition to a normal strike train
  • A separate tune-selection mechanism on clocks offering more than one air
  • Pinned barrels analogous to those found in musical boxes, on comb-type musical clocks

Terminology

  • Quarter chime — a short musical phrase played at each quarter hour before the hour strike
  • Whittington and Westminster chimes — the two most common English quarter-chime tune sets
  • Comb — a tuned steel strip plucked by pins on a rotating barrel, as used in musical boxes and some musical clocks

Known variations

  • Quarter-chiming clocks (bell-based)
  • Comb-type musical clocks
  • Multi-tune selectable musical clocks

Collecting notes

Quarter-chiming English longcase and bracket clocks with a choice of chime tunes are a well-established collecting sub-field; the condition and completeness of the bell or comb set materially affects both sound quality and value.
