The Transpose Dialog

When you click on (or tab-to and activate) the “Transpose” button, at the upper-right of any performance pane, a dialog box similar to the following will appear:

Screen-shot of the "Set Transpose-Interval / Key-Signature" dialog box.
The first four drop-boxes are used to specify the key-signature. If you change any of them, the other three will change to correspond to the change you selected. The 5th drop-box is not affected by what is specified in the first 4 drop-boxes.

You would use the first drop-box in the case where a singer explains that it is pitched too high (or low), and asks if you could transpose it down (or up) a certain number of semi-tones (half-steps).

You can do this with a smile, accommodating the singer, because the fingering is the same in every key-signature, and you just play it (in the new key-signature) the way you are used to, in the former key-signature.

The second drop-box is probably the one you will use the most. To use it, you count how many sharps (#) or flats (b) are in any clef of the written music, and specify the number you counted. In the case above, it's 3 sharps.

Another way of specifying the key-signature, is by its major key name. You use the 3rd drop-box to do this. In the case above, it's “A Major”. If someone specifies a key-signature with just its letter-name, it implies it's the major key.

Another way of specifying the key-signature, is by its minor key name. You use the 4th drop-box to do this. In the case above, it's “F-sharp Minor”. The key-signature of a minor key-signature will always have “minor” as part of its name. A letter-name by itself, implies major.

Note: You'll probably notice in some drop-boxes there is more than one way of specifying the same thing. In such cases, it's usually best to choose the option that requires the lesser amount of transposition.

You seldom use the 5th drop-box, and normally leave it set to “C instrument”, which means the KeyMusician Keyboard (like the piano, or cello) produces its music in concert-pitch, with no transposition.

The case where you would use 5th drop-box, is where the music you are playing from was written for some other type of instrument, such as a B-flat trumpet, or an F horn.

The “Affected Panes” radio button, controls whether the key-signature and/or instrument-type specified, is to be done in only the current performance pane, or whether it is to affect all performance panes.

When you click (or tab-to and activate) the “OK” button, the specified change is made. If you click (tab-to and activate) the “Cancel” button, no changes are made. If you click (tab-to and activate) the “Help” button, this information appears.

Note: the use of an instrument type other than the default “C instrument” is not supported in the Chords pane, and the code will prevent you from accidentally doing so.

For most cases, this is all you need to know about the Transpose dialog.

More Information For Using The 5th Drop-Box

The “Music Played is For” drop-box can change the sound of the KeyMusician Keyboard, so that you can play written music for many types of musical instruments, such that when played together, it will sound as one harmonious whole.

It means you can play from band or orchestra parts, or even parts in an orchestra score, and it will go with an audio file of a band or orchestra performing the piece.

It changes the sound of the KeyMusician Keyboard according to the following table:
