Music class for use with leJOS NXJ playNote and playTone methods

As an exercise I've written a Music class that makes writing NXT melodies easier by allowing note values to be passed instead of frequencies. I used this page as a reference: http://www.phy.mtu.edu/~suits/notefreqs.html. Any suggestions are appreciated. I hope someone finds it useful! Here's a little vid: http://blogs.hewittnet.org/robotics/files/2013/10/IMG_1008.mov

import lejos.nxt.Sound;
public class Music {
    private static String[] notes = { "C3", "C#3", "Db3", "D3", "D#3", "Eb3",
            "E3", "F3", "F#3", "Gb3", "G3", "G#3", "Ab3", "A3", "A#3", "Bb3",
            "B3", "C4", "C#4", "Db4", "D4", "D#4", "Eb4", "E4", "F4", "F#4",
            "Gb4", "G4", "G#4", "Ab4", "A4", "A#4", "Bb4", "B4", "C5", "C#5",
            "Db5", "D5", "D#5", "Eb5", "E5", "F5", "F#5", "Gb5", "G5", "G#5",
            "Ab5", "A5", "A#5", "Bb5", "B5", "C6" };
    private static float[] frequency = { 130.81f, 138.59f, 138.59f, 146.83f,
            155.56f, 155.56f, 164.81f, 174.61f, 185.0f, 185.0f, 196.0f,

            880.0f, 932.33f, 932.33f, 987.77f, 1046.5f };

        }

    }
}

Here is an example implementation of the class:

import lejos.nxt.Sound;

public class MusicTest {
    private static String[] melody = { "C4", "D4", "E4", "C4", 
        "E4", "C4",    "E4"};

    public static void main(String[] args) {
        Music music = new Music();
        for (int i = 0; i < melody.length; i++) {
            music.musicPiano(melody[i], 300);
            System.out.println(melody[i]);
        }
        Sound.pause(300);
        for (int i = 0; i < melody.length; i++) {
            music.musicTone(melody[i], 300);
            System.out.println(melody[i]);
        }
    }
}
