1 /* 2 *This program interprets melodic lines given in ABC notation as a 3 * chromesthete might. 4 * 5 * A Pitch class will be defined, and will take center stage in the 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 pitch 11 * class. The duration will correspond to the duration of the note. 12 * 13 * For this 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 * A,B,C,D,E,F,G, A B C D E F G a b c d e f g 23 * 24 * Google ABC music representation if you would like to know more about it 25 */ 26 27 package chromesthesia1; 28 29 import java.util.Scanner; 30 import javax.swing.JOptionPane; 31 import javax.swing.SwingUtilities; 32 import painter.SPainter; 33 34 public class Chromesthesia { 35 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 //ADDED NOTES F,G,A,B 103 Pitch pitchMiddleF = new Pitch("F", painter); 104 pitches[9] = pitchMiddleF; 105 Pitch pitchLowF = new Pitch("F,", painter); 106 pitches[10] = pitchLowF; 107 Pitch pitchHighF = new Pitch("f", painter); 108 pitches[11] = pitchHighF; 109 Pitch pitchMiddleG = new Pitch("G", painter); 110 pitches[12] = pitchMiddleG; 111 Pitch pitchLowG = new Pitch("G,", painter); 112 pitches[13] = pitchLowG; 113 Pitch pitchHighG = new Pitch("g", painter); 114 pitches[14] = pitchHighG; 115 Pitch pitchMiddleA = new Pitch("A", painter); 116 pitches[15] = pitchMiddleA; 117 Pitch pitchLowA = new Pitch("A,", painter); 118 pitches[16] = pitchLowA; 119 Pitch pitchHighA = new Pitch("a", painter); 120 pitches[17] = pitchHighA; 121 Pitch pitchMiddleB = new Pitch("B", painter); 122 pitches[18] = pitchMiddleB; 123 Pitch pitchLowB = new Pitch("B,", painter); 124 pitches[19] = pitchLowB; 125 Pitch pitchHighB = new Pitch("b", painter); 126 pitches[20] = pitchHighB; 127 return pitches; 128 } 129 130 private static Pitch find(String token, Pitch[] pitches) throws Exception { 131 for (int i = 0; i < pitches.length; i = i + 1) { 132 Pitch pitch = pitches[i]; 133 if (pitch.abcName().equals(token)) { 134 return pitch; 135 } 136 } 137 throw new Exception("### PITCH" + token + "NOT FOUND"); 138 } 139 140 private static void display (Pitch[] pitches) { 141 for (int i = 0; i < pitches.length; i = i + 1) { 142 System.out.println(pitches[i].toString()); 143 } 144 } 145 146 private static void playMelody(String input, Pitch[] pitches) throws Exception { 147 Scanner scanner = new Scanner(input); 148 while (scanner.hasNext()) { 149 String token = scanner.next(); 150 Pitch pitch = find(token,pitches); 151 pitch.play("1"); 152 } 153 } 154 155 //INITIALIZATION, CLEANUP, GETTING INPUT, ERROR MESSAGING 156 157 static private void showErrorMessage(String message) { 158 miro.setVisible(false); 159 JOptionPane.showMessageDialog(null, message); 160 } 161 162 private static void initialization() { 163 //ESTABLISH THE PAINTER AND GIVE IT A SUBSTANTIAL BRUSH WIDTH 164 miro = new SPainter("Chromesthesia",500,500); 165 miro.setVisible(false); 166 miro.setBrushWidth(7); 167 //ESTABLISH THE CHROMESTITIC PITCH CLASS OBJECTS 168 pitches = establishPitches(miro); 169 display(pitches); 170 } 171 172 private static String getInput() { 173 miro.setVisible(false); 174 String label = "Please enter a melody in ABC notation, or EXIT...
