turning organ player
Fritz von Uhde: Lyra box man in Zandvoort

a Drehorgel, or also lyra box, is a mechanical music instrument.

As can be prove since beginning 18. Century is the Drehorgel in all countries of Europe as instrument of the road musicians and Gaukler in addition, - in particular inEngland and France - when church and salon instrument admit.

The structure of the Drehorgel corresponds in principle to a stationary whistle organ. It consists the whistle work, the bellows work, the Windlade and the play mechanism of a housing in that is accommodated. With the help of a crank or a oneFlywheel over connecting rods the drawing bellows referred with leather are operated, which produce the wind (compressed air). The wind is stored, calmed down in magazine bellows and brought with spring action on a constant pressure.

Over the Windlade, which contains a multiplicity of valves, the whistle work stands. Each valvea clay/tone (a whistle or several whistles of different design) is assigned. The number of the tones can be different with Drehorgeln (for instance from 16 to 45). These valves are headed for by the play mechanism. This can happen pneumatically, mechanically or electromagnetically. The whistles are those a church organsimilarly.

With mechanical/pneumatic control also the programme carrier is moved by the rotating motion of the crank.

Contrary to a manually playable organ the control of the tones is taken over by a programme carrier, which is in the play mechanism. The oldest form of the programme carrier is the pin roller.This is well-known since the antiquity. Since beginning 20. Century the punched tape has and/or. the hole cardboard the pin roller replaced. A pin roller (usually replaceable) can contain music pieces (six to eight are common) up to twelve. The Lauflänge of the piece of music is limited by the roller extent. ThroughPunched tapes or hole cardboard (both exchangeably) the Spieldauer is nearly unlimited; likewise with electronic controlling of the whistle work. Since beginning of the 1970er years the Microchip is used as digital storage medium for music in the building of turning organs.

By change of the rotating speed, effect on the wind pressure and the use of differentWith larger instruments interpreting representing of the music on pneumatically steered Drehorgeln is possible for tone qualities (registers).

With some models the electronic control does not permit influence on the music. Whether the crank is moved forward or backwards, slowly or fast: the music soundsalways directly. Other building types against it react to a change of the rotating speed with appropriate effect on the rendition speed of the music piece.

Electronically steered Drehorgeln can be synchronized over radio or by cables. All organs play either the same notes of the piece of music, or however they take over individual partsa kind orchestra score. Here the art of the Arrangeurs or programmer is in demand. The rendition does not require musical being able of the organ turner.

On the other hand the synchronous play with two or several punched tape-steered Drehorgeln of the same type of building presupposes exercise and ability paired with musi potashty and rhythm feeling. For this are resemblesor according to manufactured punched tapes at the market available.

In completely Europe turning organ player - in particular during special “turning organ days” - arises publicly. One can engage many turning organ players also privately for appearances.
