For low notes, the chest voice resonates more in the chest or perhaps even in the abdomen, shifting its resonance further and further upwards as the notes climb up the scale.

Resonators – Chest/Head (68 kb)

A powerful chest voice in all registers is typical of modern music styles.

Full voice in all registers (74 kb)

Of course, there are some tunes that call for a lyrical head voice, but the gigantic sound that is typical of singers like Whitney Houston, Aretha Franklin, Mariah Carey, Celine Dion, Anastacia, etc., is based on their ability to maintain a chest voice up to the highest notes. That is by no means easy because, above a certain pitch (around e1), the voice tries to change over to the head voice. Preventing this from happening requires special training. Without practice, higher registers require more pressure and constantly "force" the voice into the range of the head resonances.

For female singers in particular, it is important to concentrate on the low resonances in the chest and to further develop the voice there. In the registers of the pure chest voice (D to h) below c1, the vocal range is just about at its limits.

Generally speaking, deep resonances give the voice more sound, for both male and female singers. Therefore, before you try to extend your limits upwards, you should first of all try to stabilise and strengthen your normal chest voice – its range may well go much lower than you think. Don't always think "upwards" but try to develop a more balanced sound.

Different resonators – with depth, with less depth, without depth (43 kb)

Untrained voices lack one thing above all: depth – in their sound and in their expression.
