Students learn the letters at full speed, but with extra space between the letters at first. You could think of the musical score above as a sort of transcription of the Farnsworth method of teaching Morse code. If you have any suggestions, particularly related to Lilypond, please let me know. ![]() I may play around with this and try to improve it a bit. No doubt there’s a better way, but this worked. remaining contestants through their rehearsal, showing them their marks. My way around this was to make it label two consecutive measures with H, then in image editing software I turned the second H into an I. Candles floated on the lily pond, and all the seating had been removed to make. I tried several tricks, and Lilypond steadfastly refused to label a measure with ‘I’ even though I’ve seen such a label in the documentation. The first way is boxed measure numbers inline every five bars, kind of like how rehearsal numbers are often indicated, but the current measure count rather than a sequentially increasing number or letter. ![]() That meant that the labels I and all subsequent letters were one ahead of what they should be, and the final letter Z was labeled AA. Rehearsal mark questions Im duplicating a part that has a couple of different ways of indicating locations. I used rehearsal markings to label the measures, but there was one problem: the software skips from letter H to letter J. I made the image above with LaTeX and Lilypond.Īdding the letters above each measure was kind of a hack. In fact, they’re not really hearing letters at all but recognizing the shape of words. An H, for example, four dits in a row, sounds like a single rough sound. Some people can copy Morse code at more than 50 words per minute or more, but at that speed they’re not hearing individual dits and dahs. That would imply that copying Morse code at 20 wpm is pushing the limits of human hearing. ![]() ![]() But according to this video, the shortest duration people can distinguish is about 50 milliseconds. You could rewrite the music above as follows, but it’s all an approximation.Īccording to Wikipedia, “the dit length at 20 words per minute is 50 milliseconds.” So if a sixteenth note has a duration of 50 milliseconds, this would mean five quarter notes per second, or 300 beats per minute. This doesn’t make much difference because individual operators have varying “fists,” styles of sending Morse code, and won’t exactly follow the official length and spacing rules. So the sheet music above would be more accurate if you imagined all the sixteenth notes are staccato and the dotted eighth notes are really eighth notes followed by a sixteenth rest. But there’s also a space equal to the length of a dot between parts of a letter. Officially a dash is three times as long as a dot. I picked the E above middle C (660 Hz) because it’s in that range. Morse code is often at a frequency between 600 and 800 Hz. A dash is supposed to be three times as long as a dot, so a dot is a sixteenth note and a dash is a dotted eighth note. Here’s the Morse code alphabet, one letter per measure in practice there would be less space between letters. Maybe this has been done before, but I haven’t seen it: Morse code in musical notation.
