Few people realize the intricate and detailed steps required to produce an accordion. About 6000 parts are combined in a process involving hundreds of man hours to bring an accordion to life.
Skilful craftsmanship and carefully chosen materials are vital components of a fine quality accordion. No short cuts are possible when producing instruments which are truly responsive and capable of the most magnificent musical range and colorations.

Engineering and design problems take endless hours as the instrument's evolution results in advancements. Here, in an informal European atmosphere, countless years of experience in accordion construction are pooled to arrive at solutions which will enhance the accordion's position in the music world.
These are various stages in the assembly of the accordions' treble keyboards - similar in either piano key or button style. The treble plates must be carefully channeled for trouble free operation. Great skill is required to assemble a first-class keyboard mechanism and even more care must be taken if the treble includes tone chamber construction.


Injection molding produces the black keys for sharps and flats. Precision dies are used to make a variety of functional and ornamental components of the accordion.
make the treble registers respond instantly by activation the slides which open and close appropriate tone holes, permitting the desired reed combinations to sound. Here, the molded levers are fitted to the treble switch assembly on the grille and the inner mechanism of the treble registers is adjusted for smooth operation.

Many stages of bass case construction require much careful work, such as this painstaking shaping on a circular spindle cutting machine, the final woodwork detailing, and trimming the smoothly-contoured plastic covering.
The sea of bass buttons, which confounds the novice, is no mystery to these craftsmen who carefully assemble the intricate bass machine mechanism. Rods and pistons, brass pins and mechanical-noise insulators are individually positioned to create the wonderous bass machine, some of which provide innovations such as convertor or chromatic free bass and pedal tones in addition to the stradella system.
The various reed operations are numerous, beginning with a huge
power press which die-stamps the plates, the making of the multi-chambered reed blocks, the precise die-cutting of the reed tongues, selection provino-tuned reeds and carefully waxing them onto the blocks to assure air-tight fit.
The bellows, which enable the instrument to offer an amazing range of expression, are constructed of special cardboards, lined with fabric and leather "diamonds" which are positioned in the corners of each fold. All outer sides have folds tape-reinforced, bonded with specially formulated hot glue and finished with precision pinched chrome corners. Here, electroplating the bellows' corners in a chrome bath and pinching them into positions shown.
After the treble and bass selections have been assembled, the reeds in each are tuned by a craftsman. Following this, the instrument will be fully assembled and both sides will be tuned to each other to complete the process.
The accordion must be able to play a sustained note very loud or very soft and respond instantly to the slightest bellows movement. Response of all reeds should be balanced on a chord. Blocks must be seated perfectly to avoid air loss or waste, They should have multiple coats of high-lustre varnish to enhance tone and protect against warpage.
