In 1777, Mozart referred to the tangent piano as the "Spattisches Klavier," after the maker of tangent pianos, Spath. Other names included the Italian cembalo angelico, and the French clavecin harmonieux et celeste. This is all evidence that the tangent piano spread throughout Europe. By the earliest decade of the 19th century, Spath tangent pianos were sent all over the globe and given a wide 6 octave range, which enabled it to compete with the piano. At the same time, the fortepiano began to eclipse the harpsichord and clavichord as the keyboard instrument of choice.
The creation of the tangent piano, and the fortepiano, was a result of an attempt to remedy the lack of dynamics in harpsichord sound. Both the tangent piano and fortepiano offered a variety of sound that was appealing to the changes in classical music, which featured more expressiveness and intensity than the harpsichord could offer. The tangent piano had a short life in popularity, and dropped off somewhere in the late 1700s or early 1800s. The fortepiano, however, buried the harpsichord in popularity by 1800. It then slowly evolved to the massive modern iron-framed giant of 88 keys. The tangent piano's popularity lasted for such a short time, that very little music was written for it. It is possible that CPE Bach's keyboard concerti were written for this instrument or for the fortepiano. In either case, the tangent piano is an appropriate choice for the keyboard instrument in the concerti. In addition, other sons of the famous German composer JS Bach wrote pieces expressly for the tangent piano. Miklos Spanyi recently released a recording for them on the tangent piano.
