Chords in a Key Chart
As worship musicians who read from chord charts, we often want to know what chords we will be using in a particular key. It might surprise you to learn that there are only 6 main chords in each key - 3 major chords, and 3 minor chords. For example, let’s look at the key of C:
The C scale is C-D-E-F-G-A-B-C, and each of the chords shown above is built on a note of the scale. For example, the C chord is built on the first note of the scale (C), and it uses every other note in the scale (C-E-G). The Dm chord is built on the second note of the scale (D), and it uses every other note (D-F-A). The Em chord is built on the third note of the scale (E), and it also uses every other note (E-G-B). This process is repeated for the F, G, and Am chords. (You will notice that we did not include a chord for the seventh tone of the scale, the B. This is because the chord that is built on B is neither major nor minor; it is diminished, and it is rarely used in worship piano.) This topic is explained in more detail in the Beginning Worship Piano course.
Every chord can be given a number. The first chord is called the 1 chord, the second is 2 (or 2m, as the 2 chord is always minor), etc. The 1, 4, and 5 chords are major in every key; and the 2m, 3m, and 6m chords are minor in every key. This numeric notation is referred to as the Nashville Number System (or simply the number system) and is explained in more detail in the Early Advanced Worship Piano course.
Here is the entire chart for all 12 key signatures:

If you would like to learn how to use these chords in your playing as well as inversions, accompaniment patterns, and more, check out my Worship Essentials courses. This unique approach combines a simple, easy-to-follow method of learning the piano along with teachings on the heart of worship - and it has proven successful for people of all ages and levels.
Or, if you would prefer one-on-one instruction, consider online lessons. Lessons incorporate the same content of the Worship Essentials courses but have the added bonus of one-on-one coaching and instruction.
Happy worshipping!
