This lesson is quiet a simple one for beginners on piano. It's the G Major scale. Often a starter scale on piano is the C Major scale because it only uses the white keys. That makes it easy to play and easy to remember.
The scale below uses only one black key. Practice playing this scale up and down ascending. You can use just one finger, probably your thumb or first finger. Use both hands. Use both hands at the same time. The note names are given for you to learn also.
Once you get this down practice running through two octaves. In other words once you arrive at the second G note simply start the pattern again until you get to the next G.
