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