In the earlier post, I mentioned that I played the chords are F C and F when I was playing in the accompaniment mode, (or when I was sequencing the keyboard track for Strings/Guitar). Now we'll see why we chose those chords to play.
Step 1: Writing the Tune
First let's write down the keys for the tune. You can try to do this in your head, but I think writing down would help when you are trying this for the first time (I know it's a bit tedious). I'd like to include the following information:
Beat count
Lyrics
Keys ($ = previous key held)
Chords (X = possible chords position, F/C/F = matching chords)
Here's how I'd write it down (I am also filling up the chord information - see Step 2 for explanation):
1 2 3 4 5 6 7 8
---- ----- ---- ---- | ---- ---- ---- ----
Ho- -
A G
X X
[F ... same as 33-40 F] (pick these later)
9 10 11 12 13 14 15 16
---- ----- ---- ---- | s---- ---- ---- ----

Here's a picture which shows the name of the keys, if you want it for a quick reference.
Step 2: Finding the chords
Finding the chords consists of two things:
a) Positioning the chord in the rhythm cycle.
b) Matching the chord with the note
Positioning the chord
To start with, let's fix the position of the chords at the 1st beat of every rhythm cycle (X at 1, 5, 9 ...). It's always a good first guess, but keep in mind it doesn't work always. E.g., sometimes the chord can change in the 2nd, 3rd or 4th beat for a 4/4 rhythm cycle, or even change multiple times within one cycle. We'll talk about those later on.
Anyway, assuming that the guess works, now we only need to match the chord with the tune!
Matching the chord
The possibilities: To find the chord corresponding to a note, there are six possibilities - three Major Chords and three Minor Chords (ok, I'm making some mild assumptions here).
For example, say that you are on the note 'A'. If it is a Major (Happy) chord, then it is probably the 1st key of the Major Chord, or the 5th, or the 6th. On the other hand, if it is a Minor Chords, it probably the 1st, 4th or 8th key of the chord.You can quickly find the exact possibilities by numbering your key (i.e. 'A') as 1 or 5 or 8 or 4, and counting down (going left on the keyboard) and get the name of first note of the chord.
So, theoretically here are the possibilities which goes with the note 'A': A, F, D, or Am, F#m, Dm.
The probabilities: Mostly you don't need go through all the 6 chords to eliminate 5 out of them. Make the initial guesses based on the following thumb-rules:
a) Happy vs Moody: If the song is happy sounding (that's not a very scientific definition - but you will start to relate very soon) - it must be a Major chord, Otherwise, if is sounds moody or sad or creates some suspense, it may be a minor chord. So, that takes the available choices down to 3 corresponding to the note A - A, F and D.
b) Hierarchy: Chances for note corresponding to the 1st key of the chord > Chances for note corresponding to 5th (4th if minor) 1st key of the chord. > Chances for note corresponding to the 8th key of the chord. That means, to find the chord matching with the word "-To ..." (the first word in the tune with X mark, note A) we should try A, then F, and then D.
c) Family: Quite often chords for a song belong to pre-existing families - so you can limit your searches to the candidates within that family. This is the most helpful hint, once you have gained some experience (already picked up chords for 5-6 songs). Some popular families are C-F-G, Bb-Eb-F, A-D-E, etc. (I will try to add a complete list of this later).
Back to our Example:
If we apply the above ideas of probabilities and possibilities, we immediately see that the most appealing (pleasant to the ears) chords corresponding to the notes:
A, F, E, $(E), G, A, F, $(F) (starting from beat 9, corresponding to X) are
F, F, C, C, C, F, F, F
The other possibilities will sound very "weird" (e.g., (1) if you try A or D with note A, or (2) G or Eb with note G) - you can count on your musical ears for that!
Hope that was not difficult to follow! Post questions if you are still in doubt.
