Why alphabetical order matters for beginners
Most experienced operators learn morse in Koch order — a sequence optimized for sound-recognition, not alphabetical logic. Koch order starts with K and M because they contrast sharply by ear and builds from there. For received learning, Koch order is faster.
But alphabetical order has its own value for beginners. When you need to look up a letter mid-copy, you search A-to-Z automatically — the same way you look up a word in a dictionary. An A-to-Z chart is a lookup tool; Koch order is a training sequence. You need both. Use this chart on your wall or desk as the lookup reference and use the Koch method guide for your actual training sessions. The two approaches are complementary, not competing.
How to read this chart
Each card shows the letter, its morse code in dots and dashes, and a mnemonic to help you remember the pattern. A dot is a short signal (one unit); a dash is a long signal (three units). The gap between elements within a letter is one unit; between letters is three units; between words is seven units.
The ▶ button plays the letter at 15 WPM using the standard 800 Hz tone. Click it to hear how the pattern sounds rather than reading it visually — that sound-to-letter connection is what you need to build first.
When you tap ▶ and hear “di-dah,” say the sound aloud: “A — di-dah.” Do not say “dot dash.” The di-dah pronunciation is the actual signal rhythm, and memorizing the sound is the only path to fast copy.

Frequently asked questions
Is this chart the same as the ITU standard?
Yes. Every letter code on this chart matches the ITU-R M.1677-1 international morse standard. The mnemonic sentences are Morsify originals designed to help with memorization, but the dot-dash patterns themselves are the official standard used by amateur radio operators worldwide.
Why is E just one dot and T just one dash?
Because E and T are the two most common letters in English. The original morse code system (developed by Alfred Vail working with Samuel Morse in the 1830s) assigned the shortest codes to the most frequent letters to minimize total transmission time. Vail reportedly visited a print shop and counted the type drawers to determine letter frequency — a remarkably modern information-theoretic insight made without any formal theory.
Should I learn the chart before I learn to listen?
No. Reading the chart before training your ear is the single most common beginner mistake. It builds a visual-translation habit — you see a dot, you think 'dot', you search for 'dot-dash equals A' — that adds a slow mental step that never fully goes away. Instead, look at the chart, say the sound aloud, then immediately click ▶ to hear it. The goal is to hear 'di-dah' and think 'A' without any intermediate step.
