Hi, I remember reading on websites and books that say that doublebasses are relatively hard to find when compared to the almost infinite number of violinists/cellists available. Would you say that is true? My impression is that trumpets and tenor/alto saxes are abundant too, with fewer numbers of baritones. And fewer french horn players. Has there ever an occasion where there are too many doublebassists around and too many competing for limited space in an orchestra? Which orchestral instruments are the most rare?
