How to say it
Operators don’t say “dot dash” — they say dah dah dah dah dit. Saying the rhythm out loud is the quickest way to make it stick.
Mnemonic
Think: four dahs, one dit. Stressed syllables are dahs, unstressed are dits. Use it to get started, then drop it — at real speed you won’t have time to think.
Timing
1 dit and 4 dahs. A dah is three times the length of a dit, with a one-dit gap between each symbol. The whole number is 17 units long.
Where you learn it
In the Koch order DotDash uses, 9 is character number 26 of 40. You learn it by sound at full speed, with a new character unlocked each time you reach 90% accuracy.
