Class AnalysisPianoHands

java.lang.Object

eu.bandm.music.applications.feldproj.AnalysisPianoHands

public class AnalysisPianoHands
extends Object

Analyse a FeldmanProjection_n score object for multi stops and three overlapping piano events. The further is done by simple static methods. For the latter, construct an instance of this class and invoke apply(eu.bandm.tscore.model.Vox,eu.bandm.tscore.model.Vox,eu.bandm.tscore.model.Vox).

Field Summary

Fields

Modifier and Type	Field	Description
protected @Opt Rational[]	end	Contains the end point of the event currently sounding in each voice.
final FeldmanProjection_n	score	Needed to step through the time points, identify pauses, and get event ends.
protected @Opt Rational[]	start	Contains a start point of an event for each voice, as long as it is sounding.

Field Details

score

public final FeldmanProjection_n score

Needed to step through the time points, identify pauses, and get event ends.

Constructor Details

AnalysisPianoHands

public AnalysisPianoHands(FeldmanProjection_n score)

Only constructor.

Method Details

apply

public void apply(Vox harmonics,
 Vox sound1,
 Vox sound2)

Scan these three voices for three overlapping events. If a triple is found, print its beginning time point to standard output.

rat2measurenumber

public static String rat2measurenumber(Rational pos)

Converts a time point rational (0-based) to a string representation of measure number (1-based) plus internal offset as rational (iff !=0)

findMultiStops

public static void findMultiStops(FeldmanProjection_n score,
 String name,
 String vname)

Looks in the voice with the given name in the given score data for multistops. If there is at least one, the total figures are printed of double, triple, and quadruple stops.

Parameters:

score - the data

name - to identify the score in the printed output

vname - of the voide to analyse

findMultiStops1

public static void findMultiStops1(FeldmanProjection_n score,
 String name,
 String vname)

Looks in the voice with the given name in the given score data for multistops. If there is at least one, the figures are printed seperately for harmonics, pizzicato, and ordinario, to the standard output.

Parameters:

score - the data

name - to identify the score in the printed output

vname - of the voide to analyse

main

public static void main(String[] args)

Loads the tscore source for all five Projections and searches for overlapping chords in the piano voices and for multi stops in the string instruments. The results are printed to stdanard output.
