After Bach and Handel, trumpet playing declined. Haydn, the great successor of these two masters, did not do well with trumpets. When Haydn entered the service of Prince Esterhazy, music-loving prince of Austria, his orchestra at first did not include trumpets at all.
As late as 1766, the regular personnel of this orchestra, one of the foremost in Europe, consisted of six violins and violas, one cello, one string bass, one flute, two oboes, two bassoons and four horns but no trumpets or cornets. Several years later the resources of the orchestra were enlarged so that trumpets and tympani could be added when needed.
Even when Haydn did use trumpets, he scored for them so they played an octave or a sixth above the horns. To this thin arrangement he added drums for accompaniment. He probably felt the need of filling in with something, and the drums seemed the most appropriate.
Mozart, who was at first Haydn’s pupil but whose genius lifted him to a place above his master, seemed to share Haydn’s dislike for trumpets. This antipathy for trumpets was due to an extremely sensitive nature. Until Mozart was ten years old, the sound of the trumpet was excruciatingly painful to him, and he could not endure it.
