Today I will give a reference table for standard chords including jazz chords. To be able to construct these quickly we will explain what the notation means:

Some of the notation uses numbers, like X^9, these represent scale degrees of a standard major scale:

Scale Degrees | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |

Intervals | 0 | 2 | 4 | 5 | 7 | 9 | 11 | 0 |

continuing to go further yields

Scale Degrees | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 |

Intervals | 0 | 2 | 4 | 5 | 7 | 9 | 11 | 0 |

Also note that for the symbol X9, we can see it uses the intervals 0 2 4 7 10,
so it's a combination of X7 plus the 9th (remember 9th is the interval 2 based
on the tables above). Also note that for X13 we have the intervals

0 2 4 5 7 9 10 so it's combining X9 with the 13th scale degree. In practice we
don't need to play all those notes at once to get the idea of X13 across, in
general we can remove intervals which represent simple harmonics (being a
harmonic means that it is very similar to the root tone), so it can be
simplified to 0 2 5 9 10 (there are other options).

So when we have a chord with a number after it, it specifies all notes up to that N should be added (like in the X13 example above), but if we wrote Xadd11 for example we would just add the 11th scale degree and not everything up until the 11th scale degree so it would be 0 4 7 5.

Note when a chord is notated as alt (for altered) we take the chord and additionally add any subset of the set {1, 3, 6, 8} to the chord (those are intervals)

Here is the table of all of the chords:

Given any 7 11 2 5 you can replace it by a 1 5 8 11. The reasoning behind this substitution is that it maintains the same chord quality with two matching notes
