Abstract
The сolla parte technique is one of the nexus between the Baroque and early Classical orchestration. In the article the connection between the orchestral style of Haydn’s early symphonies and the previous Baroque epoch is retraced by the example of colla parte technique. The colla parte phenomenon is considered rather extensive — not only as written instructions for an instrument to play by the part of another one, but also as a technique of total doubling even in the absence of a corresponding designation. The special attention is given to the questions connected with rendering the bassoon and viola parts which, as a rule, were not written in the score in detail, while playing colla parte.
