I would highly recommend either buying, or borrowing from the library, a book on basic music theory and/or learning to play the piano. The piano keyboard is laid out very logically and can actually help you understand the theories involved. Each key on the keyboard represents a half step. The white keys are the "natural" notes, as in A-B-C-D-E-F-G, which is the musical alphabet. The black keys are the sharps and flats, or " accidentals". From a white key to an adjacent black key is one half step, and there are 12 half steps in an octave. Note that there are no black keys between the notes B and C and E and F. That knowledge alone can help you find your place on the keyboard. Two half steps make a whole step. This system of half and whole steps becomes very important when it comes to scales and intervals. With H being a half step and W being a whole step, a Major scale would be....W-W-H-W-W-W-H. So, an one octave C Major scale, which has no sharps or flats, would be C-D-E-F-G-A-B-C. The half steps are between B to C and E to F, where there are no black keys. Middle C is just left of the center of the keyboard on most keyboards. Also make note of the fact that some notes have 2 names. As in an A sharp is the exact same note as a B flat. This is known as enharmonic spelling, and A sharp/B flat is the black key between the white A and B keys. I know this can seem overwhelming at first, which is why I greatly recommend obtaining a book that you can sit at the keyboard and use to come to grips with the layout. Key signatures and intervals are also very important to understand. There are many good, and relatively inexpensive, beginner books available on numerous sites on the internet, and again, having hard copy at the keyboard makes things much easier in my opinion. Good luck with your musical adventures. :)
