Timing rules

Morse timing is built on one unit: 1.2 divided by WPM seconds. A dot lasts 1 unit, a dash 3, gaps between symbols are 1 unit, between letters 3, and between words 7. At 18 WPM a dot is just 67 milliseconds, which is why fast code sounds like chirps.

Learning with sound

Start at 15 to 20 WPM character speed and learn the rhythm of each letter rather than counting dots. The tone is 700 Hz, the classic sidetone pitch radio operators train with.

... --- ... is easy to recognize and remember. It was chosen as the distress signal because of its simple pattern, not because it stands for words.
