On a piano, there are 2 different types of notes you need to know about which are the white keys and the black keys. I will explain them both in detail and what makes them different.
The White Keys

The white keys on a piano are the most used keys on a piano. These keys are also referred to as natural keys because of how smooth they sound when played. Each key is assigned a letter from the alphabet in the order C - D - E - F - G - A - B and they cycle in that order across the piano. The easiest way to remember where the notes are is to remember the D note is always inbetween the 2 black keys on a piano. Remembering these notes is needed to play on a piano and once you remember where the notes are, you can move on to understanding the black keys.
The Black Keys

Test your memory
To make sure you really do know where all the notes are placed, i will give you two helpful tips keep you remembering:
- Identify the white keys individually. Practice naming them untill you can find each note without counting from C and remember that the D note is always between the two black notes. If you need help remembering this, just remember the phrase 'Dog in a kennel'.
- Its not important to remember each sharp or flat by name just yet, but remember how to locate the using the white natural keys.
