Koch Lesson 6: Add the Letter P
Last verified: August 2026 · Unique to this step — not a duplicate of the hub.
K -.- M -- R .-. S ... U ..- A .- P .--.
Why this step
Up to now every letter was one to three elements. P is four: dit, dah, dah, dit — a palindrome. It teaches you to hold a longer shape without dropping back to counting.
What to hear
P opens like A (dit-dah) then continues with another dah and a closing dit. If you stop after two elements you will call it A. Let the letter finish.
Drill
Active set: K, M, R, S, U, A, P. When P is new, the trainer still mixes old letters so P does not become the only sound you wait for.
Letter groups you can type in the translator once the ear is warm: PA, UP, SP, AP
Pitfall
Four-element panic. If P always loses, keep WPM; shorten the session to ten minutes rather than slowing dits.
