A–Z reference
A dot lasts one unit and a dash lasts three. Start with E, T, I, A, N and M, then listen to each complete character as a rhythm.

Signal spacing
Morse is a timed language. A dot lasts one unit and a dash lasts three units. Parts of the same character are separated by one unit, letters by three units, and words by seven units. Written Morse normally uses a space between letters and a slash between words.

Charts are useful for reference, but fluent operators recognize the sound of a whole character. Listen to .- as “di-dah” for A instead of thinking “dot, dash.” Practice in short daily sessions, mix characters you already know with one or two new ones, and avoid tracing a visual decision tree in your head. The goal is to hear a rhythm and recognize it immediately.
