The figure below shows what happens when the advanced setting is selected.

This menu now shows the six options, cup, throat, rim, backbore, stem and outer shape. Taken together, these provide access to all the parameters which may be adjusted on a PeakTone® mouthpiece. Each of these is a drop-down menu which, when clicked, will offer access to settings for each of the named mouthpiece sections.These will only be discussed in broad terms here as they are covered in detail in the Parameter Manual section which is in the form of manual and detailed guide to all the parameters. You can access that Parameter Manual Index directly but it is probably better to read about them in general in this section first as all the necessary links to parameter topics are provided here.

The Cup options provide the settings which change the internal shape of the cup. You can read about what the cup does in the Mouthpiece Cup Section. Clicking the cup option will display the options shown below.

The options provided grant you access to the parameters which affect the internal shape of the cup. The top two of these, cup diameter and cup depth have been explored in Modifying your Mouthpiece but other are a little more complex, such the inflection point vertical and inflection point horizontal as they interact with each other to form the mouthpiece cup. These settings are explored in the Parameter Manual but, so you can have a little experiment with them, they’re included in the diagram below.  The changes will be made when you move the sliders. You may also enter a value in the edit box below the slider and the change to the cup will be made when you click outside this box, having made a change. Once the slider has been moved away from the default setting, the reset button will appear and clicking this will reset the slider value to the default setting. The meaning of inflection point is discussed in the Parameter Manual – Inflection Point Section._

The shoulder angle setting acts pretty-much on its own and it can be explored the Shoulder Angle section of the Parameter Manual.

The Throat

The Throat options provide the settings which change the shape of the throat. You can read about what the throat does in the Parameter – Throat Section. Clicking the throat option will display the choices shown below which allow you to adjust the throat diameter, the radius between the cup’s shoulder and the throat entrance and the depth of the throat itself. This latter feature is a cylindrical section created between the cup and the backbore.

You can experiment with these settings using the live settings below. The entire mouthpiece is shown in this case as the throat depth setting is given a range of zero to one, where the maximum setting means that the throat is extended to the exit end of the mouthpiece.

The effects of throat settings are discussed in the Mouthpiece Throat Section.

The Rim

The Rim options provide the settings which change the shape of the rim. You can read about what the rim does in the Parameter – Rim Section. Clicking the rim option will display the choices shown below.

These settings allow you to adjust the rim width, the rim bite radius between the top of the rim and the side walls of the cup, the rim rise, the rim thickness and the position of the rim’s peak. The diagram below shows how these settings affect the rim’s shape. The_ rim width_ is simply the width between the inner surface of the cup and the outer wall of the mouthpiece. Widening this provides more support for the lips. The rim bite is the radius at the top corner of the cup and the rim rise__, the amount by which the upper surface of the rim rises above what would be a flat rim. The rim thickness is simply an external dimension, providing a cosmetic change, although some people do feel that the bulk of the mouthpiece affects its performance characteristics. The rim peak position setting controls where the highest point of the rim is located across the face of the rim.

The rim settings may be experimented with on the active diagram below. width, bite, rise, thickness, position

The Backbore

The backbore options provide the settings which change the contours of the backbore. You can read about what the throat does in the Parameters – Backbore Section. Clicking the backbore option will display the choices shown below. The diagram below shows the backbore settings.

These three settings are very closely related to each other so they are discussed alltogether in the Parameter – Backbore section

</div>

The Stem

The stem options provide the settings which change the outer contours of the stem, the portion of the mouthpiece which sits inside the instrument’s receiver. You can read about what part the stem plays on the mouthpiece in the Parameter – Stem Section. Clicking the stem option will display the choices shown below. The diagram below shows the stem settings.

Three of these settings, the stem lower diameter, stem receiver depth and stem receiver diameter are very closely related to each other so they are discussed alltogether in the Stem Taper Parameters section, the other parameter, stem type is discussed in the stem type section.

The function of the settings is not discussed here but you may experiment with them in the active diagram below.

The Outer Shape

The outer shape option  provide a single setting which changes the overall length of the mouthpiece. Clicking the contol shown below.

Dragging the slider will increase and decrease the overall length of the mouthpiece within the max/min limits given below this slider. This is discussed in more detail in the overall length section but you may experiment with it in the active diagramm below.
