Fundamental Ranges

The Fundamental Ranges page configures the colored bands drawn behind the Staff View, used to mark the frequency ranges of choral voices and of singable overtones. You can pick from several built-in profiles, edit the included ranges, or add new ranges of your own.

Voice Range Profiles

The dropdown at the top of the page selects the active voice-range profile. Built-in profiles are read-only; user-defined copies can be edited, renamed, and deleted freely.

SATB

Shows the four classical choir voice ranges: Soprano, Alto, Tenor, Bass.

Standard Voice Range Profile

The four choir voices plus the range of overtones that can be sung in a controlled manner by consciously amplifying specific harmonics.

Overtones NG / L

The singable overtones split by technique used to produce them:

NG technique: Uses the entire oral cavity without the tongue. Suited to lower overtones.
L technique: Uses the tongue to divide the oral cavity into two chambers. Used to produce the higher overtones.

Managing profiles

Three buttons to the right of the profile dropdown manage the profile library:

Rename / Copy: Save the current profile under a new name. Built-in profiles must be copied before they can be edited.
Delete: Delete the currently selected profile. Built-in profiles cannot be deleted.
Read-only: Mark the current profile as read-only to prevent accidental edits.

A visible checkbox lets you hide the entire current profile from the Staff View without deleting it. Hidden profiles still appear in the profile dropdown so they can be restored later.

Editing the ranges

The property browser in the middle of the page lists every range in the current profile. Each range has its own group of editable properties below its name.

Inner and Outer values

Each range fades in from the background color over a short frequency band, holds at full color across the main band, and fades out at the upper edge.

Outer value (low / high): The frequency at which the range starts to fade in from the background, and the frequency at which it has fully faded out at the top.
Inner value (low / high): The frequency at which the range reaches its full color, and the frequency at which it begins to fade out at the top.

The Outer and Inner values together produce a soft-edged colored band that does not visually shout the boundaries — useful when the boundary is itself fuzzy (different sources disagree about the exact range of an alto, for example).

Color Type

Each range is drawn in one of two semantic colors:

Voice: Used for normal singing-voice ranges (Soprano, Alto, etc.).
Overtone: Used for ranges of singable overtones.

The actual RGB values for Voice and Overtone are configured on Fonts and Colors, under Colors / Staff View / Range Voice and Range Overtone. Editing them there changes every range that uses that color in every profile.

Adding, removing, and reordering ranges

Four buttons next to the property browser manage the list of ranges within the current profile (only enabled for editable, user-defined profiles):

Add: Append a new range with default values. Edit it in the property browser to set the frequency boundaries and color type.
Remove: Delete the selected range from the current profile.
Move Up / Move Down: Reorder the ranges. Order matters when ranges overlap because later ranges are drawn over earlier ones.
