Learn Morse Code: How to Read, Listen and Practice
Start with the rhythm of a few letters. Then read groups, preserve the gaps and try a short listening exercise.
What is Morse code?
Morse code represents characters with short and long signals: dots and dashes. International Morse uses the same code for uppercase and lowercase Latin letters. It encodes characters, rather than translating between spoken languages. Sound, light and visible marks can carry the same pattern.
Dots, dashes and the gaps between them
Choose a dot as one time unit. A dash lasts three units. Silence or darkness is part of the code too: one unit inside a character, three between characters and seven between words. At a slower speed, every unit gets longer while these basic ratios stay the same.
| Element | Dot units |
|---|---|
| Dot | 1 |
| Dash | 3 |
| Within a letter | 1 |
| Between letters | 3 |
| Between words | 7 |
How to read a written message
Keep each group together. For example, .- is A, but . - is E followed by T. In this website’s written notation, a space separates letters and / separates words. Read .... .. as H I; it is the word HI. Use the chart to look up a whole group, or follow its dot-left, dash-right tree.
How to learn the sound
Begin with E (one short tone) and T (one long tone), then A (short-long) and N (long-short). Listen to each complete rhythm before checking the chart. Add a few letters at a time and practice short words. Use a slower playback speed at first; the main translator also offers Farnsworth spacing to give more time between characters.

Reading light, tapping and blinking
Light carries the same timing: a short illumination is a dot, a longer one is a dash, and darkness separates them. Short and long eye closures can demonstrate the pattern in a blinking exercise. Tapping needs an agreed distinction between short and long actions; identical instant taps alone do not preserve Morse timing. The lamp below illustrates generation, not recognition of a flashing video.
A short history and modern uses
Samuel Morse and Alfred Vail helped develop practical electrical telegraphy. Their Washington–Baltimore demonstration took place in 1844. International Morse later became a shared code for radio communication. It is still used in amateur radio and as a learning or puzzle activity. The SOS pattern is a distinct distress-signal example; this website does not transmit it.
Listen to HELLO and watch its rhythm
The written slashes mark word gaps, not extra tones. Listen first, then compare the letter groups below. Try the lamp to see the same timing.
