Daubeny, in his book, Orchestral Wind Instruments, offers his opinion on the valve trombone: “The slide trombone, the only wind instrument that is equally capable with the violin of the most exact accuracy of intonation, was unsafe from desecrating hands and fell a ready victim to the valve mania….The characteristic trombone timbre seems to be in some way lost by the addition of valves, and intonation can never more than approximate to the degree of accuracy obtainable with the slide” (Daubeny 96).
