You should begin with a straight posture while being seated at the piano. Your posture will contribute to your ability to read the sheet music as well as lift your foot to press on the pedal if needed. With your shoulders back, bend your elbows and slightly extend your arms to allow maximum room for arm movement and ability to play both bass and treble keys easily.
Like body posture, hand posture is also a key element to being able to play piano with ease and comfort. Wrists should be slightly lifted and fingers should be faintly bent to allow quick movement and ease.
Finally, extend fingers to allow more room for easier playing of both the black and white keys. The wider you spread your fingers, the more distance you can cover to allow easier and comfortable playing.
You are finally ready to begin to play or practice music on this beautiful instrument! I hope this tutorial aided you in your ability to play the piano! Thank you for reading and stay tuned for more music fun.
