What key is this song in?

Type the chords in the order they appear. We find the key and number every chord in it. The first and last chords decide between a major key and its relative minor.

Why the key helps

• Numbers G, C, D, Em in G are I, IV, V, vi: the same progression in any key.
• Transposing count the half steps to a key that suits your voice.
• Soloing stay inside the key's scale for melodies and solos.
