Mit einem Kopfdurchmesser von 8,5 mm besitzt der Concert Piano den kleinsten Tip der drei Modelle, gleichzeitig aber das h\u00f6chste Eigengewicht. Diese Kombination erm\u00f6glicht eine hervorragende Klangprojektion bei sehr geringer Auslenkung im Handgelenk. Buzz Rolls, Open Rolls und Singles lassen sich dadurch besonders gut kontrollieren. Gefertigt wird der Concert Piano aus Red Hornwood, einem speziell f\u00fcr Rohema in Deutschland hergestellten Buchenschichtholz. Das Material bietet eine besonders hohe Kontinuit\u00e4t bei Dichte und Reboundverhalten und macht den Einsatz gef\u00e4hrdeter tropischer H\u00f6lzer \u00fcberfl\u00fcssig. F\u00fcr eine angenehme Haptik, gute Griffigkeit und optimale Kontrolle erh\u00e4lt der Stock in einem zweistufigen Verfahren ein \u00d6l-Wachs-Finish.
