However, except for some organ pipes the bore of most wind instruments is not cylindrical and the open ends are flanged. Of these, only the conical and cylindrical pipes have resonant frequencies that are multiples of the fundamental. L has exactly the same resonant frequencies as an open cylindrical pipe of the same length has. We shall see later that many wind instruments are part cylindrical, part conical, and part flanged. Thus in playing, in tuning, and in construction the only variable is the length.
All wind instruments consist of a sound generator and a resonant air column, or cavity.
Air-reed instruments such as the flue organ pipe, flute, piccolo, recorder, flageolet, and fife. Single mechanical reed instruments such as the reed organ pipe, clarinet, saxophone, and bagpipes. Double mechanical reed instruments such as the oboe, English horn or coranglais, oboe d'amore, bassoon, and contrabassoon. The human voice. As a source of musical sounds, the human voice is the most versatile of the musical instruments in its possible variations of pitch, loudness, and quality of sounds that it can produce.
