The material and function keys are outstanding. The sound is crisp and stable. It is a pro quality instrument with a beginner price. I take this opportunity to consult with you the following situation: One of the melodic I have is the P25D (current version P25F), the melodica is rightfully the little sister of the Yamaha Pianica. In the review of the site is classified as beginner melodica, Question: Is this Because the Least amount of keys? having the same good quality as his sisters 32 and 37. Maybe they should change their classification considering this. Thank you very much for your comment. Greetings.
