This button closes the window of the editor.
This mask prompts that some non-chord tones should be resolved to a chord tone. The editor uses the following rules to compute the mask: The Motive can begin with either a chord or non-chord note. If the non-chord note is located in the up-beat or in the Motive start, on the next step it should smoothly resolve into the chord note. If the non-chord note is taken by a leap, on the next step it should smoothly resolve into the chord note. The non-chord note may follow another non-chord note if the interval between the first non-chord note and a previous chord note is second. The second non-chord note should smoothly resolve into the chord note. Those pitches, which obey to the above mentioned rules, have the blue background. In that way, the editor recommends to choose only these pitches on the current step. Also a small arrow points to the pitch that is recommended for the choice. The background colour of the other pitches is a light tint of the red and blue colours. Thereby the editor does not recommend to choose these pitches on the current step.
This button switches on the 'chromatic edition' mode. The mode allows to enter any note, even if the note does not belong to the tonality of the melody.
Use this ScrollBar control to have the access to the all four octaves of the editor pitch diapason.
Use this button to move the editor to the next Motive.
Press this button to move the editor to the previous Motive.
