1 /* 2 * This program interprets melodic lines given in ABC notation as a chromesthete might. 3 * 4 * A Pitch class will be defined, and will take center stage in the processing. 5 * 6 * interpreting a melody in ABC notation will amount to flashing colored rectangles for 7 * prescribed durations, while sounding the pitch! The color of the rectangle will correspond 8 * to pitch class The duration will correspond to the duration of the note. 9 * 10 * For this second version of the program, the duration will be held constant at 1 beat. 11 * 12 * Three sorts of images will appear on the screen, the chromesthetic output box, a text input 13 * box, and an error message box. Simplicity of design is rendered by permitting only one box 14 * to be on the screen at a time. 15 * 16 * ABC represents notes in a manner consistent with these examples: 17 * C, D, E, C D E c d e 18 * 19 * Google ABC music representation if you would like to know more about it. 20 */ 21 22 package chromesthesia1; 23 24 import painter.SPainter; 25 import javax.swing.JOptionPane; 26 import javax.swing.SwingUtilities; 27 import java.util.Scanner; 28 29 public class Chromesthesia { 30 31 //INFRASTRUCTURE FOR THE PROGRAM - LAUNCHING A "GRAPHICS" THREAD 32 public static void main(String[] args) { 33 SwingUtilities.invokeLater(new chromesthesia1.Chromesthesia.ThreadForGUI()); 34 } 35 36 private static class ThreadForGUI implements Runnable { 37 @Override 38 public void run() { 39 new chromesthesia1.Chromesthesia(); 40 } 41 } 42 43 public Chromesthesia() { 44 interpreter(); 45 } 46 47 //FEATURED VARIABLES 48 private static SPainter miro; 49 private static Pitch[] pitches; 50 51 //THE INTERPRETER 52 public static void interpreter() { 53 initialization(); //miro and pitches 54 55 while (true) { 56 String input = getInput(); 57 if (input.equalsIgnoreCase("EXIT")) { 58 break; 59 } else { 60 try { 61 playMelody(input, pitches); 62 } catch (Exception ex) { 63 showErrorMessage(ex.toString()); 64 } 65 } 66 } 67 cleanup(); //miro has to go 68 } 69 70 //METHODS PERTAINING TO THE CHROMESTHETIC PITCHES 71 private static Pitch[] establishPitches(SPainter painter) { 72 Pitch[] pitches = new Pitch[21]; 73 74 Pitch pitchMiddleC = new Pitch("C", painter); 75 pitches[0] = pitchMiddleC; 76 77 Pitch pitchLowC = new Pitch("C,", painter); 78 pitches[1] = pitchLowC; 79 80 Pitch pitchHighC = new Pitch("c", painter); 81 pitches[2] = pitchHighC; 82 83 Pitch pitchMiddleD = new Pitch("D", painter); 84 pitches[3] = pitchMiddleD; 85 86 Pitch pitchLowD = new Pitch("D,", painter); 87 pitches[4] = pitchLowD; 88 89 Pitch pitchHighD = new Pitch("d", painter); 90 pitches[5] = pitchHighD; 91 92 Pitch pitchMiddleE = new Pitch("E", painter); 93 pitches[6] = pitchMiddleE; 94 95 Pitch pitchLowE = new Pitch("E,", painter); 96 pitches[7] = pitchLowE; 97 98 Pitch pitchHighE = new Pitch("e", painter); 99 pitches[8] = pitchHighE; 100 101 Pitch pitchMiddleF = new Pitch("F", painter); 102 pitches[9] = pitchMiddleF; 103 104 Pitch pitchLowF = new Pitch("F,", painter); 105 pitches[10] = pitchLowF; 106 107 Pitch pitchHighF = new Pitch("f", painter); 108 pitches[11] = pitchHighF; 109 110 Pitch pitchMiddleG = new Pitch("G", painter); 111 pitches[12] = pitchMiddleG; 112 113 Pitch pitchLowG = new Pitch("G,", painter); 114 pitches[13] = pitchLowG; 115 116 Pitch pitchHighG = new Pitch("g", painter); 117 pitches[14] = pitchHighG; 118 119 Pitch pitchMiddleA = new Pitch("A", painter); 120 pitches[15] = pitchMiddleA; 121 122 Pitch pitchLowA = new Pitch("A,", painter); 123 pitches[16] = pitchLowA; 124 125 Pitch pitchHighA = new Pitch("a", painter); 126 pitches[17] = pitchHighA; 127 128 Pitch pitchMiddleB = new Pitch("B", painter); 129 pitches[18] = pitchMiddleB; 130 131 Pitch pitchLowB = new Pitch("B,", painter); 132 pitches[19] = pitchLowB; 133 134 Pitch pitchHighB = new Pitch("b", painter); 135 pitches[20] = pitchHighB; 136 137 return pitches; 138 } 139 140 private static Pitch find(String token, Pitch[] pitches) throws Exception{ 141 for (int i = 0; i < pitches.length; i++) { 142 Pitch pitch = pitches[i]; 143 if (pitch.abcName().equals(token)) { 144 return pitch; 145 } 146 } 147 throw new Exception("### PITCH " + token + " NOT FOUND"); 148 } 149 150 private static void display(Pitch[] pitches) { 151 for (int i = 0; i < pitches.length; i++) { 152 System.out.println(pitches[i].toString()); 153 } 154 } 155 156 private static void playMelody(String input, Pitch[] pitches) throws Exception { 157 Scanner scanner = new Scanner(input); 158 while (scanner.hasNext()) { 159 String token = scanner.next(); 160 Pitch pitch = find(token, pitches); 161 pitch.play("1"); 162 } 163 } 164 165 //INITIALIZATION, CLEANUP, GETTING INPUT, ERROR MESSAGING 166 static private void showErrorMessage(String message) { 167 miro.setVisible(false); 168 JOptionPane.showMessageDialog(null, message); 169 } 170 171 static private void initialization() { 172 //ESTABLISH THE PAINTER AND GIVE IT A SUBSTANTIAL BRUSH WIDTH 173 miro = new SPainter("Chromesthesia1", 500, 500); 174 miro.setVisible(false); 175 miro.setBrushWidth(7); 176 //ESTABLISH THE CHROMESTHETIC PITCH CLASS OBJECTS 177 pitches= establishPitches(miro); 178 display(pitches); 179 } 180 181 private static String getInput() { 182 miro.setVisible(false); 183 String label = "Please enter a melody in ABC notation, or EXIT ..."; 184 String input = JOptionPane.showInputDialog(null, label); 185 miro.setVisible(true); 186 if (input == null) { input = ""; } 187 return input; 188 } 189 190 static private void cleanup() { 191 System.exit(0); 192 } 193 194 } 195
