Research has been conducted on prominent mid-twentieth century French trumpet concertos and their composers. Jolivet, Bozza, and Tomasi have all been the subject of research. Charles Chaynes' music is equally valuable to modern trumpet repertoire as that of Jolivet, Bozza, and Tomasi. Chaynes' exclusion from research leaves a void in resources available to future trumpet students. A study of Charles Chaynes and his trumpet concertos is essential to preserving the history of the valve trumpet's young modern repertoire. Lack of understanding of Chaynes' trumpet concertos can only lead to misconceptions when interpreting these pieces. The thirty-nine year gap between Chaynes' Trumpet Concerto No. 1 and Trumpet Concerto No. 2 is a remarkable time span between major compositions, and examining the works gives insight to the evolution of the trumpet concerto throughout the twentieth century. This project highlights Charles Chaynes' contribution to the trumpet repertoire from both the beginning and end of his compositional career, and fills the research gap concerning his concertos. It includes correspondence with Charles Chaynes and others, in order to gain information not found in common source materials. It highlights examples from each concerto that are representative of the composer's compositional style.
