Context : I play this song Kal ho na ho, title song, on F major key. the F scale i follow is D shaped which starts from 3rd Fret 4th string(D).
heres is scale:
String | frets
6 | 3 5 7
5 | 3 5
4 | 2 3 5 (3rd fret 4th string is the key of F)
3 | 2 3 5
2 | 3 5 7 (6th fret 2nd string is another F key,1 octave higher)
1 | 3 5 7
Problem : In the title line of the song which says "kal HO na ho", when first "HO" is played, it goes out of the scale. Its only that particular note. It falls on the 5nd string 6th fret, which is not a part of the scale.
Question : Is it possible in a song to have a note which is out of a scale ? If yes, there are there any rules when using some out of the scale notes?
I hope i made my query as clear as popssible. Kindly help me clarify this.
