Detailed Description

Class used for transposing a set of notes for the given interval.

Licensed under the GNU GENERAL PUBLIC LICENSE. See COPYING for details.

This is a control class used for making a transposition of a set of music elements, contexts or even the whole score sheet.

Use: 1) Create a CATranspose class 2) Pass the music elements you want to transpose in the constructor or by calling addMusElement() or addContext(). 3) Transpose the elements by calling transposeByKeySig(), transposeByInterval(), transposeBySemitones() or reinterpretAccidentals().

◆ reinterpretAccidentals()

void CATranspose::reinterpretAccidentals ( int type )

Changes note accidentals dependent on type: 1) If type==1, sharps -> flats 2) If type==-1, flats -> sharps 3) if type==0, invert

This function also changes Key signatures dependent on type, if their number of accidentals is greater or equal than 5 or lesser or equal than -5.

◆ transposeByInterval()

void CATranspose::transposeByInterval ( CAInterval interval )

Transposes the music elements by the given interval. If the interval quantity is negative, elements are transposed down.

◆ transposeByKeySig()

void CATranspose::transposeByKeySig	(	CADiatonicKey	from,
		CADiatonicKey	to,

	)

Transposes the music elements from the given key signature from to the key signature to in the given direction. Direction can be 1 for up or -1 for down.
