Morse Code Alphabet
A clickable Morse chart where every letter, digit and signal plays its own sound – ideal for learning the code by ear rather than by staring at dots.

What it does
The Morse Code Alphabet page on Unscramble Words 4U sets out International Morse in groups: the 26 letters, the numbers 0 to 9, punctuation, accented letters and procedure signals (prosigns) such as SOS, AR and SK. Tap any code and it plays. Tabs along the top switch the chart to the Morse systems used for Greek, Russian, Hebrew, Arabic, Persian, Korean (SKATS) and Japanese (Wabun), and the usual sound and light settings let you change the speed, spacing, pitch and volume.
Alongside the main chart there are 36 single-character pages, one for each letter A–Z and each digit 0–9, linked from the chart. Each one plays the character, gives its ‘di-dah’ rhythm, counts its dots, dashes and time units, points out letters that are its mirror or opposite, and lists everyday words that begin with it, each with a play button. Together they make a tidy reference for pupils, Scout and Guide groups, escape-room makers and anyone starting out.
How to use it
- Open the alphabet chart. International Morse is shown first.
- Tap a letter to hear it. Try to remember the rhythm as a whole, not the number of dots.
- Scroll down for numbers, punctuation, accented letters and prosigns.
- Use the tabs to see another writing system’s Morse table.
- Click a letter in the row of links to open its own page, with memory tips and example words to play.
- Open the sound and light settings to slow things down, add Farnsworth spacing or change the tone.
More tips
- Numbers are a neat pattern: every digit has five signals, so learning them together is quick.
- Pair opposites together. A (.-) and N (-.) are mirror images, which helps both stick.
Ideas for the classroom and home learning
- KS1 (5–7)Letter of the day: open one letter page on the board, play it, and have children copy the rhythm with claps or a drum.
- KS2 (7–11)Pattern hunt: look at the number codes and ask pupils to predict the code for 7 before checking it on the chart.
- KS3 (11–14)Data and design: count the signals for each letter, compare with how often letters appear in English, and discuss why common letters were given short codes.
- KS3 (11–14)Languages and culture: compare the Greek or Russian tab with the International chart and notice where letters with similar sounds share a code.
Questions
How should a beginner learn the Morse alphabet?
Learn by sound. Play each letter, say its rhythm aloud and practise a few minutes daily, beginning with short letters such as E, T, N and A.
What are prosigns?
Procedure signals are short runs of signals sent without the usual letter gap, used to manage a message – for example AR for the end of a message and SK for the end of a contact. SOS is the famous one.
Does the chart work for screen reader users?
Each chart button has a spoken label describing its code in words, such as ‘dot dash’, so it can be explored with a screen reader as well as by sound.
Can I print the chart?
The tool is designed for sound, so pupils get the most from it on a device. You can still print the page from your browser for a wall reference.
