Memory mnemonic

BOOOOOM-ba-da-da

Say it aloud with the stresses shown. The phrase carries the same dit/dah rhythm as the Morse for B. Once the rhythm sticks the dots and dashes follow.

This is the widely-circulated Scout-meeting variant. Many teachers develop their own — the words don't matter, only that the chosen phrase carries the same dit/dah rhythm.

About B in Morse code

Pattern: -...
Length: 9 Morse units
Spoken as: Bravo (BRAH voh)
In English text: 1.5% of letters — the 20th most common
Sent backwards: ...- is V
Dots ↔ dashes: .--- is J

B takes 9 units to send. 11 letters are shorter and 6 others are the same length. Alfred Vail reportedly counted the type in a printer's case and gave the shortest codes to the letters used most, so frequency and length roughly track each other: B is the 20th most common letter and has the 12th-shortest code.

How long B takes to send

Speed	Unit length	B takes
5 WPM	240 ms	2.2 s
13 WPM	92 ms	0.83 s
20 WPM	60 ms	0.54 s
25 WPM	48 ms	0.43 s

Standard PARIS timing: one unit is 1200 ÷ WPM milliseconds; a dot is 1 unit, a dash 3, and the gap inside a character 1. Add 3 units between letters and 7 between words.

Easily confused with

These are one dot or dash away from B. Mishearing a single element — or clipping one off the end — turns B into one of them, so they are worth drilling side by side.
