Haydn's Trumpet Concerto in E flat is one of the most famous works in the classical trumpet repertoire. Written in 1796 for Anton Weidinger, a prominent Viennese trumpeter, the concerto was intended to demonstrate the capabilities of the newly invented keyed trumpet, which enabled performers to play chromatic notes with greater precision. This innovation marked a clear departure from the limitations of the natural trumpet, which could only produce notes within the harmonic series. Haydn's concerto not only highlights the technical advances of the instrument, but also reflects his compositional mastery. The concerto is divided into the traditional three movements: Allegro, Andante and a finale marked Allegro. The trumpet part is both lyrical and virtuosic, with scales, arpeggios and ornamental runs that demonstrate the keyed trumpet's ability to master chromatic passages. The energetic themes reflect Haydn's characteristic wit and elegance, while the interplay between soloist and orchestra demonstrates his skills as an orchestrator. Hummel's Trumpet Concerto in E major (generally transposed to E flat in modern performances) is also a cornerstone of the trumpet repertoire and an excellent example of late Classical music. It was written in 1803 for the same dedicatee as Haydn, Anton Weidinger, and stylistically bridges the gap between the Classical and Romantic periods. Hummel was a contemporary of Beethoven and a pupil of Mozart, and his concerto is filled with elegance, technical brilliance and expressive lyricism. Hummel composed the concerto during his tenure as court composer to Prince Esterházy (Haydn was actually his predecessor in this office). Weidinger, a tireless advocate of the keyed trumpet, worked with composers to expand their repertoire, and Hummel's concerto is one of the best examples of this effort. The three movements of the concerto are Allegro con spirito, Andante and a rondo marked Allegro molto. Together they emphasize the versatility of the keyed trumpet while adhering to classical ideals of balance and clarity. A majestic orchestral introduction sets the stage before the trumpet enters with a declarative theme that showcases its extended range. Contrasting lyrical and virtuosic passages allow the soloist to demonstrate his technical mastery, and Hummel's use of chromaticism, made possible by the new instrument, gives the work a distinctive flair and novelty.
