I've been practicing to play song 'Har Ghadi Badal Rahi He'
from the movie 'Kal Ho Na Ho', I extracted notes/swaras of that music by hearing.
I got these notes/swaras combinations: C D E F G A A# B
8 notes / swaras in total, which is contrary to what I learnt; a song/music cannot exceed 7 notes.
Side note: I searched over Internet for notations as well, many websites had wrote 8 notes.
How is that possible [8 notes]? Genuinely looking for answers.
