Over the last 15 years Pirastro has developed new concepts and ways of constructing strings, had important experiences in string technology and has gained new expertise. During that development phase, they came out with such popular strings as the Obligato®, Evah Pirazzi® and Passione®. Today they have a different knowledge and new techniques at hand to design a nylon core string set. As a result they have newly constructed all of the Tonica® strings except for the E steel wound with aluminum string. These changes result in an overall improved string set. Sound Characteristics The Tonica® has now a livelier and more round sound, which is open and direct with less side noises. The projection and brilliance have been upgraded. This excess of brilliance, however, does not mean that the Tonica® has lost its warmth. The set harmony is better. The response is easier and faster. Playing pianissimo has considerately improved. All bow strokes are possible resulting in smooth crossings from one note to another. Easier right hand articulation and tone attack.
