This is a follow-up post from the previous post regarding building extended chords. I will be documenting how I come up with various voicings for [A Foggy Day](https://en.wikipedia.org/wiki/A_Foggy_Day).
## Rules of thumb
- Repeating the melody an octave below is okay
- Avoid the fifth in favour of other intervals (including for the melody)
- Tritone subtitutions where suitable
- When the melody is on the fifth Reharmonisation it is possible to change the tonic to suit a more interesting interval.
## Bar 1
### Step 1 - Tonic and Melody
Figure out the following bits:
- Tonic: `F`
- Chord: `Fmaj7`
- Melody: `C` (the `5th`)
### Step 2 - 3rd and 7th shell voicing
- 3rd: `A`
- 7th: `B`
### Step 3a - Add Alterations
You also need to make sure the intervals between the alteration and the melody note is suitable. See the previous blog post for suitable alterations.
### Step 3b - Consider Context
#### Step 3b.1 Dominant V
Any dominant 7th chords acting as the fifth of the key centre can be switched with a tritone substitution, melody allowing.
