How do I improve my rapping and singing skills?

Incorporate wordplay with good delivery and a message between the lines. Use passion and an intricate sound to make a good song. Most of all, focus on hard work and practice. Rapping and singing is poetic, so take an interest in lots of poetry, writing poems yourself. Turn these into entertaining lyrics and modify them in a way that you can deliver them in a musical manner. Always writing rap lyrics in a notebook is helpful. This way you'll be able to freestyle and this will make your delivery more consistent as you develop a unique style of rapping.
