Start to find the C, if your melody start on that you can skip all the black keys on the piano. Did you know most melodies consist of notes that is 1 or 2 steps up or down from the previous, so it is a great help when trying to play a melody. So if you can hum a song slowly and listen if it is one note up or down, and 1 or 2 steps, then you can start take out songs by ear.

Want to see something AMAZING? Check out the World's current population and live count here.

Population growth is determined by two factors: Birth and Death Rate. The birth rate is the number of babies born each year per 1000 people, and the death rate is the number of people who die each year per 1000 people. 

When we compare the two factors, we can conclude whether the population is growing/ increasing (when Birth Rates exceed Death Rates) or decreasing (when Death Rates exceed Birth Rates).  The natural increase or decrease of the population depends on the difference between the birth and death rates. The rate of natural increase, or decrease, is the birth rate minus the death rate
