Here's an arrangement of “Only Girl” by Rinanna. It starts off with the keyboard riff that is ever present throughout the verses. Then it goes to the proper intro with a left hand variation of the keyboard riff. I have include the bass line of the verse as a variation in the 2nd verse. The chorus is a bit tricky rhythmically, but it is only a 2 bar pattern. Once these two bars are mastered you are good for the whole chorus. Powerful bass octaves come in later on in the chorus. The 2nd verse leaves the keyboard riff and uses the bass line in the left hand. The level of difficulty is somewhere between intermediate and advanced intermediate.
