Yes, you can learn the violin as an adult. No age is too old to start learning the violin.
However, adults might initially be dissatisfied with their sound, but it's typical for beginners. Maintaining a positive mindset is crucial. Adults may need more time to adopt the correct posture due to lesser flexibility than children, so regular stretching exercises are recommended.
Despite daily life pressures possibly affecting consistency, practicing even 30 minutes daily can lead to improvement. For structured learning, seeking a professional violin teacher is advised.
