Changing keys
Near top left of the screen there is a spin box for selecting any
key, and two option buttons for choosing either a major or a minor key. If you
select the name of a key which doesn't exist, such as D# major, or Db minor, an
error message to this effect will pop up. If you have specified an exam board
and a grade, only the keys required for cadences in this grade will be
selectable. Otherwise, all legal major and minor keys (up to 7 sharps or
flats) are demonstrated.
Changing the voicing.
Under Voicing, there are 4 option buttons for Vocal (Soprano Alto
Tenor Bass), Piano, Close 3 note, and close 4 note. Only one of these may be
selected, and the demonstration will employ that voicing.
Navigation buttons
At the foot of the screen there are the two usual buttons for navigation to the
previous and the next theory topic, according to the learning guide for your
selected exam board and grade (if any). In addition, there is a
yellow button to switch to a screen for using cadences to harmonize a
melody, and a lavender button to
go to the topic on dominant and other 7th chords.
