Fundamental Ranges
The Customize Fundamental Ranges Dialog lets you change the background of the
Staff View, where the different ranges of normal singers and of overtone
singers can be displayed.
You choose from several predefined profiles through the list box on the
right:
This profile shows the normal four choir voice ranges Soprano, Alto,
Tenor, and Bass.
This profile shows the four choir voice ranges, and the range of overtones
that are singable in a controlled manner (by consciously amplifying
specific overtones).
In this profile the singable overtones are divided by the technique used
to produce them. The NG-Technique uses the entire oral cavity without the
tongue and is more suitable for the lower overtones. The L Technique uses
the tongue to divide the oral cavity into two separate chambers. This
technique is used to produce the higher overtones.
The predefined frequency ranges are only approximations, and there are
different opinions about what constitutes the range of singable
overtones, and the choir voices. You can select the ranges that you
want to display by changing the start and end frequencies for each voice.
This switch can be used to completely disable the display of the ranges
when they are not needed, so that the Staff View will only show the music
notes.
The Outer value specify the point where the voice starts to fade
in from the background color, and the Inner value is the point
where it will reach the full color.
