Why B matters
B starts few common words and isn't high-priority to learn early. Its morse is memorable for being the reverse-structure of V (three dots then a dash) and the exact reverse of D (dash then two dots).
Memorization tip
“BOOT-to-it” — a long dash followed by three quick dots.

The history of B
B comes from the Phoenician beth, meaning house, originally drawn as a simple floor plan with a doorway. The Greeks adopted it as beta, source of the modern word 'alphabet' (alpha + beta). The closed double-loop shape we know today was settled by Roman scribes carving inscriptions in stone. In English, B sits comfortably in the middle of the alphabet but trails badly in frequency, accounting for only about 1.5% of running text.
B in CW operating
B has no special prosign role in international morse, but its dash-then-three-dots shape is one of the easiest 'long' codes to copy because the leading dash gives the ear time to reset. American operators historically used B-codes (a parallel system to Q-codes) for routine traffic, though those have largely fallen out of use except in a few maritime nets.
What position 21 means in practice
B at position 21 means roughly one B for every sixty-five characters of real English. At 20 WPM that's about one B every five seconds — sparse enough that you can spend extra cognitive effort on it without falling behind. This is precisely why most instructors push B late in the Koch sequence: the rare letters can wait. The downside is that real-text drill gives you very few B repetitions, so you have to seek out drill material specifically engineered to include B (callsign exchanges, words like 'be', 'but', 'back') if you want the letter solid before contest-grade speed builds.
How to drill it
Drill B back-to-back with V (three dots then a dash) — they are mirrored around the dash position and the brain confuses them roughly half the time at first. The trick is to count: B has the long pulse first, V has it last. Say 'BOOT' for B, 'beth-o-ven' for V.
Most-confused with: V, D, 6 — drill them together.
