While the softer strings on classical guitars are better-suited for young fingers, we can understand how some children may not be interested in those instruments — especially as they’re more synonymous with older styles of music. Acoustic guitars will probably resonate better with aspiring players, as they can be heard in all kinds of contemporary music!
Although the somewhat abrasive metal strings can make the first couple of weeks of playing quite uncomfortable, your child will start to develop calluses on their fingertips with practice, and eventually gain more finger strength and confidence. Acoustic guitars can also come in different sizes, with mini/travel-sized acoustics particularly popular — even with adults.
There are lots of reputable brands that make affordable beginner acoustic guitars. EastCoast instruments are particularly good, offering incredible value for money. Fender and Epiphone also produce a variety of starter acoustic guitars — with cool finishes to boot! Some entry-level acoustic guitars can also feature electronics which allow you to amplify them through speaker systems. These are known as 'electro-acoustic guitars', and they're great if your child wants to perform at school recitals.
