Sound

How it works

Each lesson is a few minutes; most people learn the alphabet in a few weeks of daily practice.

  1. Full speed, two characters

    Start with K and M at your target speed, so you learn each one as a sound, never by counting.

  2. Copy by ear

    10 groups of 5 characters a lesson. Type what you hear; each group is scored letter by letter.

  3. 90% adds one

    Get 90% across a lesson and the next character joins. Every answer also feeds the daily review.

Tips

  • Never write dots and dashesWrite only the letter you hear.
  • Keep the speed up18 to 20 WPM characters; slow the Farnsworth spacing if it feels fast.
  • Short and daily10 to 20 minutes a day beats a long session once a week.
  • Missed one? Let it goDon’t stop to puzzle it out: catch the next character instead.
  • ReviewThe daily review brings back each character just before you’d forget it.
  • Farnsworth spacingCharacters at full speed with wider gaps: raise it as you improve.

Frequently asked questions

About the koch course

A way to learn Morse code devised by the psychologist Ludwig Koch in the 1930s: you learn at full character speed from the start, beginning with two characters and adding one each time you copy 90% correctly. It teaches you to hear each character as a sound rather than count its dots and dashes.

With 15 to 20 minutes a day, most people learn all the letters and numbers in a few weeks to a couple of months. Copying at higher speeds comes with more practice.

No: take the placement test. It plays groups with more characters at each stage, and the course starts after the last stage you pass.

The characters are sent at full speed but the gaps between them are stretched, so you have time to think without the characters themselves slowing down. Raise it towards your character speed as you improve.
