Figure 4.37. Scale Settings


On this dialog you can select range, type and orientation of the frequency scale. Most of those settings can also be found on the toolbar.

Frequency Scale

Scale Range

This is the lowest and highest note or the lowest and highest frequency that are displayed the piano and Analyzer Views. The scale range can also be changed by clicking and dragging the frequency scale in the main view, or by using the mouse wheel in that view.

Frequency Display

This determines if the frequency scale is linear or logarithmic.

Linear and Logarithmic Frequency Scale

Figure 4.38. Linear and Logarithmic Frequency Scale


Figure 4.38 illustrates the difference between the linear (left side) and logarithmic (right side) frequency scale. Both sides show the same frequency range from about 80Hz to 1100Hz, which corresponds to the note range from E2 to C6.

When the scale is linear, consecutive harmonics have the same distance on the screen, but the piano keys get wider for higher frequencies.

With the logarithmic frequency scale, all piano keys have the same size, but higher harmonics are spaced more and more closely than the lower ones. The logarithmic scale represents how the ear perceives pitch. Towards the lower end of the scale, we can distinguish very small frequencies and hear them as different notes. On the upper end of the scale, each note covers a much wider frequency range. The logarithmic scale is therefore more suitable for analyzing music, as it shows much more detail in the lower note range.

Orientation

This setting simply determines whether the frequency scale is aligned horizontally or vertically.

Musical Notes

This group of settings controls how note names are shown on the piano keyboard and on the overtone sliders.

Accidental

This determines if the notes on the black keys of the piano are displayed with the sharp or flat sign. You can also right-click into the Staff View to switch the accidental.

Concert Pitch A

Here you can set the frequency of the concert pitch that is used as a reference for all other tones. By default, the concert pitch A is 440Hz.

Notation System

You can choose between three different notation systems:

Helmholtz Notation

This system is used mainly in German speaking countries. The notes on the piano range from A2 to C, and then from c-c5. Notice the use of both upper and lower case.

Scientific Notation

This notation is more common in English speaking countries. The notes on the piano range from A0 to C8.

Piano Keyboard Notation

In this system, the keys are numbered from 1 to 88 as they would appear on a real piano, counting white and black keys. This notation is mainly used by piano tuners.

Draw note frequencies in Analyzer View background

If this option is checked, thin lines will be drawn in the Analyzer View background that represent the frequencies of notes on the piano.
