When arranging music I feel intros can be tricky to come up with. I don’t just want to play the last line of the song as an intro. That can be boring, and coming up with something new can sometimes sound out of place for the song.
One thing I have done to change up an intro is change octaves on the last note of a line. Take “I Feel My Savior’s Love” for example. Look at the first line (line of the title). Instead of playing the normal F on “love” you play it an octave higher. Can you hear playing that higher note while your left hand is playing ascending notes leading you into the song?
I’ve found this technique useful for changing up intros, but it could very well be useful at other points of an arrangement too. Try it out!
