So far, we have developed your depth of sound and head resonances as well as your feeling for sounds in the jaws, palate and throat. As you become more and more aware of these sounds, you will learn to control them. As a singer, you are dependent not only on a stable body awareness but also on the acoustics of the room you are in. The way your voice sounds in the room can have a very decisive influence on your feeling for phrasing and intonation. Rooms with strong acoustic damping without audible reflection give the voice a "sterile" atmosphere, whereas halls with strong reverberation have the effect of suppressing the fine details of the sound and making it seem indifferent. The room raises the resonances of the voice into a further dimension, and the sound reaches the listener's ear via the room. The room contains air which also vibrates, in turn causing reflections. Make sure that you are familiar with the acoustic conditions of the room in which you are singing.
