If you want to play an E scale, then, it's E, F, G, A, B, C, D, E. The pattern for a minor scale is whole, half, whole, whole, half, whole, whole. Or, as I like to think of it, start skip next skip skip next skip skip. A C minor scale is C, D, Eb, F, G, Ab, Bb, C. This is the natural minor scale. There are two other kinds of minor scales, too: harmonic and melodic. Minor scales are fun to play because they sound different than most of the music we hear, which tends to be based on major scales. Minor scales can sound creepy or sad, but you can play them to be cheerful and interesting, too. It all depended on what you want to do. Once you're comfortable with the building blocks of music, you'll be able to play piano any way you want. You won't just be following music by rote, but actually understanding it, and that's makes all the difference.
