The only drawback was that it was really too noisy in some areas... :)
However, we were impressed by some learning tools:
- breathing / blowing control accessories, which are especially useful at teaching wind instruments;
- various accessories for musical therapies Feeltone;
- there were different card and board games with musical thematics (especially nice was Music Work Out), designed to develop various skills or understanding. We also discovered that there are many such useful games, designed for computer tablets;
- various online music sharing platforms (e.g. Music Play Along), especially useful for composers, and of course for performers, as help when learning to play.
