The Major 7th

11 semitones — bright and modern

Prove it — just do the practice exercise.
C → B 11 semitones
C
root
B
Maj 7th
The major 7th = 11 semitones:

• Found in Maj7 chords
• Just 1 semitone below the octave → sounds "close to the root"
• Creates a bright, modern, slightly dissonant sound

Example: C → B = major 7th

The difference from the minor 7th is just 1 semitone — but the character changes completely!
