The Triola is a toy instrument of VEB VEB Vermona or Klingenthaler Harmonikawerke and later the Klingenthaler company CA Seydel Söhne and belongs to the family of harmonica instruments. The instrument has colored buttons for ease of learning the sounds.
Construction
The Triola consists of a plastic housing, in which an air channel is located. This results in the blowing air from the mouthpiece into a pressure chamber above which there are valves that are opened with different colored buttons. Beneath is a reed plate on a comb, similar to a harmonica. It works on the principle of resounding Tonzunge, with bubbles and on the press of a button, a sound is generated, which is similar to the harmonica sound.
History
The Triola was developed in the early 60s as a project as part of the rationalization of the Combine for music and culture of a development team of VEB Klingenthaler Harmonikawerke and the VEB Vermona Klingenthal as children toy instrument. The design of the original Triola was tapered up in the eighties and in the production of the whole instrument was mounted on individual workstations. During the seventies the Stinima method was used to prepare the reed plates for the automation of the production process. Until then, the reed plate has been riveted by hand. As 1988/89 a new fully automated procedure was introduced, had the old design to be modified, since the production of the conical body was no longer possible. The result was today's rectangular shape. The reed plates are then tuned and semi-automatic, and is welded to the body, wherein during welding of the key action mechanism, the ultrasonic welding was employed.
Production of Triola amounted in the seventies to around 400 000 Triolas per year. How many other children she was expelled from Goldon instruments. Meanwhile, the Triola was also sold under the name Bandy. After the end of the GDR, sales of Triola broke and only in 1993 the production was resumed after manufaktureller method. Since the instrument is tuned back to individual workstations and assembled by hand, which are produced in this way is currently a few thousand Triolas per year.
Use
Even in the GDR the Triola was a popular children's instrument, which was also used in most nurseries. It was made exclusively for the market of the GDR and not exported. Therefore, its reputation in the old Länder of the FRG is quite low. Meanwhile, the Triola across the state borders of Germany is known. It will take place on attempts to use the instrument in early music education in schools and kindergartens. To Triola various music books are available which are adapted to the "Bunte -key " concept. Here, every sound has a different color and resembles the corresponding key. Thus, the player, even if he can not read the score, play a song. Ideally this is the intuitive learning of music for preschoolers.
Range
The original Triola had 12 keys and allowed the game in G major with a range of d to h ¹ ². The later instrument has depending on the model a diatonic extent of eight or twelve tones, with a complete C- major scale is playable. This allows you to play simple children's and folk songs.

In addition to the Triola other instruments of this type have been developed. The Coco was invented by Dr. Hans Hoyer Klingenthal and based, as well as the Triola, on the principle of the colored buttons. The sound, however, was produced by small plastic pipes. Among the professional instruments, which were fully chromatically playable and provided with a keyboard include the Blasharmonika 26, also called " Miki ", and Simona.
