As far as guitars are concerned, steel-string guitars are easy to learn, the kind that sings while playing. Generally, it will have a very good effect in a month or two! But your finger may hurt a little. It's not difficult to get started with the electronic piano, but it's a bit difficult to learn the staff, and boring practice is also very torturous. You should stick to it! It's not bad to learn bass, but the price may be higher. Drum sets also start from the most basic semester. If you have a bad sense of rhythm, you will feel very hard. So my suggestion is to learn steel string guitar! !
