摘要： PURPOSE:To make air columnar vibration corresponding to a pitch to be blown easy to generate and to speedily get the knack of blowing by generating the air columnar vibration basing on a musical sound signal corresponding to pitch information and exciting the wind instrument. CONSTITUTION:This device is equipped with a keyboard 1 and an oscillator 2 which is coupled with the keyboard 1 and provided on a position in the tube of the brass instrument 3 where the air columnar vibration is not impeded. When the key of the keyboard 1 is pressed corresponding to the sound of 'do' entered into a score 4, an electric signal corresponding to the sound of 'do' is transmitted from the keyboard 1 to the oscillator 2. The oscillator 2 transduces the electric signal into air vibration and the tube body of the brass instrument 3 is excited by the oscillator 2. In this state, the brass instrument 3 is blown so as to sound the 'do' entered into the score 4 through the brass instrument 3. At this time, the shape of the lips of the player and the state of expiration are so adjusted to match the excitation by the oscillator 2, and consequently the player can blow the brass instrument 3 with a correct pitch.
