public Song(java.lang.String name)

Song

public Song(java.lang.String name,
            int numMeasures)

Method Detail

getName

public java.lang.String getName()

setNumMeasures

public void setNumMeasures(int numMeasures)

getNumMeasures

public int getNumMeasures()

size

public int size()

addChordChange

public void addChordChange(ChordChange change)

Adds a chord change into the right place chronologically

getChordChange

public ChordChange getChordChange(int i)

Get the chord change at a given index. An exception is raised if the index is out of bounds

getCyclicalChordChange

public ChordChange getCyclicalChordChange(int i)

Return the chord change for a given index. Note that this is cyclical, i.e. index < 0 and index > size are valid.

intervalBetweenChords

public int intervalBetweenChords(int i1,
                                 int i2)

Return the interval between the first and second chords. Note that the value returned is always in [0, 12)

indexAtBeat

public int indexAtBeat(int measure,
                       int beat)

Return the index of the chord change at a given beat

chordAtBeat

public ChordChange chordAtBeat(int measure,
                               int beat)

Return the actual chord at a given measure and beat

removeChordChangeAt

public void removeChordChangeAt(int index)

Remove the chord change at a given index. Raise an error if the index is out of range.

removeChordChange

public void removeChordChange(ChordChange c)

Remove a given chord change. Raise an error if the change is not in the song.

beatsUntilNextChange

public int beatsUntilNextChange(int measure,
                                int beat)

Return the number of beats before the next change

distanceBetweenChords

public int distanceBetweenChords(int i1,
                                 int i2)

Return the number of beats between chord changes delta_m is the difference in measures delta_b is the difference in beats

isStrictlyDominant

protected boolean isStrictlyDominant(int i,
                                     boolean setFunction)

Return whether or not a chord is strictly dominant

isStrictlyDominant

protected boolean isStrictlyDominant(int i,
                                     Pitch tonic,
                                     boolean setFunction)

Return whether or not a chord is strictly dominant relative to a tonic

isTonic

protected boolean isTonic(int i,
                          boolean setFunction)

Determine if a given chord is a tonic. Note that this will fail if the chord is dominant, thus isDominant must be called first to determine if chord is dominant.

is_ii_in_iiVI

protected boolean is_ii_in_iiVI(int i,
                                boolean setFunction)

Determine whether a chord is a ii in a ii-V-I

caclulateChordFunctions

public void caclulateChordFunctions()

Calculate chord functions for all chords in a song

clone

public java.lang.Object clone()

Overrides:

clone in class java.lang.Object
