A child needs to discover his skills and talents so at an early age he could improve it to his best advantage. Sometimes it takes another person to discern your hidden talents and you’re lucky if someone will be able to learn it early in time. Well most often the school helps in realizing each child’s capabilities and with the influence of teachers they’re motivated to enhance it. In music there are various ways of doing it like enrolling your kid in a music workshop or letting your kid choose what he wants to play.
Parents can actually see it when their child’s eyes lit up upon seeing particular musical instruments. For boys it’s always drums and guitars that impress them quite often. Sometimes it’s because someone has endorsed a certain instrument like when Joe Satriani did with Ibanez. Anyway whatever and whoever told them what kind of instrument to play it’s always their instincts and penchant that will lead them to what they’re going to play. Not to mention that genes has a something of importance also. Love for music often runs in the blood also.
