The number of notes is a topic that causes a lot of anxiety, especially for beginners choosing their first instrument. So, to put your mind at ease, we'll explain it as clearly as possible. Nine notes are enough for most people; they're sufficient for you to express yourself and thoroughly enjoy the instrument. Having more notes on the instrument will allow you to play increasingly complex pieces and have more colors on your palette to paint your picture. So, if you want to ensure that you won't miss having more notes in the future, and your budget allows it, you can buy one with 10, 12, or even 15 notes to have the peace of mind that the complexity of your compositions will never be limited by the number of notes on your instrument. If, on the other hand, you're looking for an easy-to-play instrument and enjoy simple, relaxing music, nine or ten notes will give you everything you need.
