In the picture
- Two black keys together: the first two notes of the five-note pattern
- Three black keys together: the last three notes, which complete the pentatonic scale
- A white key: playing the white keys from C up to the next C gives the seven-note C major scale
Examples
- Playing only the black keys gives a tune that sounds right whatever order you choose, which is why many beginners improvise on them first
- Many folk songs and the opening of “Amazing Grace” use only the five notes of a pentatonic scale
Key takeaways
- Pentatonic means five notes per octave; a major scale has seven
- The five black keys of a piano octave form a pentatonic scale
