What are Morse code letters?
Morse letters are signal patterns made from short marks and long marks. A short mark is a dot, and a long mark is a dash. Each letter gets its own rhythm, so once you recognize the timing, reading Morse becomes much easier than memorizing a wall of symbols.
For example, A = .-, B = -..., and S = .... Some letters are extremely short, while others feel more musical or rhythmic when you hear them played aloud.
