1. what is a Progression = The way a song is formed .
is that right
A progression is simply a group of chords. It can be a song or just something made up.
2. What does this mean 1-4-1-5-1 or 2-5-1
The first group 1-4-1-5-1 is a progression that involes the 1 chord, the 4 chord, and the five chord of whatever key you are in with the bass note being the root of the chord. Example in key of C:
1 chord = C/C-E-G 4 chord = F/F-A-C 5 chord = G/G-B-D
I'm sure you can figure out the 2-5-1.
3. how do you know the chords to hit when playing by ear
i have the melody how do i put the progression to use
hope I'm saying this right.
Well, you just have to use trial and error. Sometimes people play word for word what the choir is singing, and sometimes people just play the music along with what the choir is singing. What I would suggest is to figure out the bass line, then the melody, then form chords under the melody, then try and play along with the CD. It also doesn't help to go and watch other people.
I hope that answers some of your questions.
