1 /* 2 * This program interprets melodic lines given in SBC notion as a 3 * chromesthete might 4 * 5 * A pitch class will be defined and will take center stage in 6 * processing 7 * 8 * Interpreting a melody in ABC notation will amount to flashing 9 * colored rectangles for prescribed durations, while sounding 10 * the pitch! The color of the rectangle will correspond to the pitch 11 * class. The duration will correspond to the duration of the note. 12 * 13 * For the first version of the program, the duration will be held 14 * constant at 1 beat 15 * 16 * Three sorts of images will appear on the screen, the chromesthetic 17 * output box, a text input box, and an error message box. Simplicity 18 * of design is rendered by permitting only one box to be on the screen 19 * at a time. 20 * 21 * ABC represents notes in a manner consistent with these examples: 22 * C, D, E, C D E c d e 23 * 24 * Google ABC music representations if you would like to know more about it 25 */ 26 27 28 package Chromesthesia1; 29 30 import java.util.Scanner; 31 import javax.swing.JOptionPane; 32 import javax.swing.SwingUtilities; 33 import painter.SPainter; 34 35 public class Chromesthesia { 36 // INFRASTRUCTURE FOR THE PROGRAM -- LAUNCHING A "GRAPHICS" THREAD 37 38 public static void main(String[] args){ 39 SwingUtilities.invokeLater(new ThreadForGUI()); 40 } 41 42 private static class ThreadForGUI implements Runnable{ 43 @Override 44 public void run(){ 45 new Chromesthesia(); 46 } 47 } 48 49 public Chromesthesia(){ 50 interpreter(); 51 } 52 53 // FEATURED VARIABLES 54 55 private static SPainter miro; 56 private static Pitch[] pitches; 57 58 // THE INTERPRETER 59 60 public static void interpreter(){ 61 62 initialization(); // miro and pitches 63 64 while(true){ 65 String input = getInput(); 66 if(input.equalsIgnoreCase("EXIT")){ 67 break; 68 }else{ 69 try{ 70 playMelody(input, pitches); 71 } catch(Exception ex){ 72 showErrorMessage(ex.toString()); 73 } 74 } 75 } 76 77 cleanup(); // miro has to go 78 } 79 80 // METHODS PERTAINING TO THE CHROMESTHETIC PITCHES 81 82 private static Pitch[] establishPitches(SPainter painter){ 83 Pitch[] pitches = new Pitch[21]; 84 Pitch pitchMiddleC = new Pitch("C", painter); 85 pitches[0] = pitchMiddleC; 86 Pitch pitchLowC = new Pitch("C,", painter); 87 pitches[1] = pitchLowC; 88 Pitch pitchHighC = new Pitch("c", painter); 89 pitches[2] = pitchHighC; 90 Pitch pitchMiddleD = new Pitch("D", painter); 91 pitches[3] = pitchMiddleD; 92 Pitch pitchLowD = new Pitch("D,", painter); 93 pitches[4] = pitchLowD; 94 Pitch pitchHighD = new Pitch("d", painter); 95 pitches[5] = pitchHighD; 96 Pitch pitchMiddleE = new Pitch("E", painter); 97 pitches[6] = pitchMiddleE; 98 Pitch pitchLowE = new Pitch("E,", painter); 99 pitches[7] = pitchLowE; 100 Pitch pitchHighE = new Pitch("e", painter); 101 pitches[8] = pitchHighE; 102 Pitch pitchMiddleF = new Pitch("F", painter); 103 pitches[9] = pitchMiddleF; 104 Pitch pitchLowF = new Pitch("F,", painter); 105 pitches[10] = pitchLowF; 106 Pitch pitchHighF = new Pitch("f", painter); 107 pitches[11] = pitchHighF; 108 Pitch pitchMiddleG = new Pitch("G", painter); 109 pitches[12] = pitchMiddleG; 110 Pitch pitchLowG = new Pitch("G,", painter); 111 pitches[13] = pitchLowG; 112 Pitch pitchHighG = new Pitch("g", painter); 113 pitches[14] = pitchHighG; 114 Pitch pitchMiddleA = new Pitch("A", painter); 115 pitches[15] = pitchMiddleA; 116 Pitch pitchLowA = new Pitch("A,", painter); 117 pitches[16] = pitchLowA; 118 Pitch pitchHighA = new Pitch("a", painter); 119 pitches[17] = pitchHighA; 120 Pitch pitchMiddleB = new Pitch("B", painter); 121 pitches[18] = pitchMiddleB; 122 Pitch pitchLowB = new Pitch("B,", painter); 123 pitches[19] = pitchLowB; 124 Pitch pitchHighB = new Pitch("b", painter); 125 pitches[20] = pitchHighB; 126 return pitches; 127 } 128 129 private static Pitch find(String token, Pitch[] pitches) throws Exception{ 130 for(int i = 0; i < pitches.length; i = i + 1){ 131 Pitch pitch = pitches[i]; 132 if(pitch.abcName().equals(token)){ 133 return pitch; 134 } 135 } 136 throw new Exception("### PITCH " + token + " NOT FOUND"); 137 } 138 139 private static void display(Pitch[] pitches){ 140 for(int i = 0; i < pitches.length; i = i + 1){ 141 System.out.println(pitches[i].toString()); 142 } 143 } 144 145 private static void playMelody(String input, Pitch[] pitches) throws Exception{ 146 Scanner scanner = new Scanner(input); 147 while(scanner.hasNext()){ 148 String token = scanner.next(); 149 Pitch pitch = find(token, pitches); 150 pitch.play("1"); 151 } 152 } 153 154 // INITIALIZATION, CLEANUP, GETTING INPUT, ERROR MESSAGING 155 static private void showErrorMessage(String message){ 156 miro.setVisible(false); 157 JOptionPane.showMessageDialog(null, message); 158 } 159 160 private static void initialization(){ 161 // ESTABLISH THE PAINTER AND GIVE IT A SUBSTANTIAL BRUSH WIDTH 162 miro = new SPainter("Chromesthesia", 500, 500); 163 miro.setVisible(false); 164 miro.setBrushWidth(7); 165 //ESTABLISH THE CHROMESTITIC PITCH CLASS OBJECTS 166 pitches = establishPitches(miro); 167 display(pitches); 168 } 169 170 private static String getInput(){ 171 miro.setVisible(false); 172 String label = "Please enter a melody in ABC notation, or EXIT ...
