Making a tonality diamond involves a few simple steps:
File:How to tonality diamond 1.png|'''Step 1: Take the numbers of an odd-limit and arrange them along two axes.'''
 
File:How to tonality diamond 2.png|'''Step 2: Using one row as the numerator and the other as the denominator, fill in the cells with the ratios they form.'''
# '''Take the numbers of an odd-limit and arrange them along two axes.'''
File:How to tonality diamond 3.png|'''Step 3: Make sure the decimal form of the ratio is between 1 and 2. If it is not, double one of the numbers until it is.'''
# '''Using one row as the numerator and the other as the denominator, fill in the cells with the ratios they form.'''  
File:How to tonality diamond 4.png|'''Optional step: to make the rows play rooted chords, one half of the diamond (not including the middle unison row) must be lowered by an octave (represented by grey cells in image).'''
# '''Make sure the decimal form of the ratio is between 1 and 2. If it is not, double one of the numbers until it is.'''
</gallery>Note: the numbers of the odd-limit are generally arranged in one of three ways: a) ascending numerically (ie, 2 3 5 7 9 11 etc) or, b) ascending by tonal order (ie 2 9 5 11 3 7), or c) ascending chordally (ie, 2 5 3 7 9 11).
Some finer points:
 
- the numbers of the odd-limit are generally arranged in one of three ways: a) ascending numerically (ie, 2 3 5 7 9 11 etc) or, b) ascending by tonal order (ie 2 9 5 11 3 7), or c) ascending chordally (ie, 2 5 3 7 9 11).
 
- in order to make the rows play rooted chords, one half of the diamond (not including the middle unison row) must be lowered by an octave.
