Charles Taylor's 1989 Christmas Lectures 4/5: Technology, Trumpets and Tunes

Описание

In his 4th lecture, Charles Taylor takes look at development and science behind wind instruments.

There has been remarkable interaction between way that instrument makers have developed instruments, way players have developed their skills for performance and way composers have used these developments in their music. This fascinating intersection of physics, craftmanship and human auditory psychology will be discussed in this lecture. Technological innovations from valves to key systems have profoundly shaped wind instrument capabilities, sound characteristics and our perception of music. This lecture will explore science behind wind instruments, looking at how these technological innovations, coupled with vibrations caused by air moving down pipes, creates sounds that we interpret as music.
