I'm trying to play music by ear, can you tell me what musical scales to use?

The primary scales you should focus on are major, minor, chromatic, and pentatonic. Major and minor scales can be used in a variety of different genres, and the chromatic scale is great for learning how to play in a specific key. Pentatonic scales are great for blues and rock music, and can be very useful in many other genres, such as jazz and folk.
