"...the most important aspect in the construction of an accordion is that of 'extracting' the sonic potential from the voices. Consequently, the more sonic potential the voices have, the more of it can be extracted in the construction of an accordion." -Lorenzo Antonelli, President & CEO of Voci Armoniche
In 2022, the year of our 100th anniversary, the BlueStar® reed has replaced our finest handmade reed as the top of the range, it exceeds in acoustic and functional potential. The new BlueStar® voices are a natural result of a new vision in the art of crafting reeds. They are the conclusion of a path of observation, study and improvement by third generation Lorenzo Antonelli. They are not considered handmade; nor a variant, or a restyling. The BlueStar® is a new voice, different from the voices of the past and those of today, because it contains substantial innovations and differences.
Compared to the handmade reed, the BlueStar® reed has specific improvements:
1) Enhanced overall timbre and functional homogeneity resulting from today's most advanced computer measuring software to enhance precision of the tongue shapes. The precision between tongue and plate has been raised to the highest possible degree. 2) Stability of the final tuning while preserving the important chargepoint.
3) Resistance to fatigue failure, improved by the thermal bluing treatment.
4) Thermal bluing of the tongues also improves the steel in its metallurgical properties, consequently improving the functional characteristics of the reeds (usability, ductility, dynamics, homogeneity).
BlueStar® is a natural evolution of innovation and technology; improving on the best characteristics of the finest handmade reed, resulting in the most refined, dynamically responsive and powerful reed produced today. When joined together with special, precision-modified reed block chambers, the result further optimizes the characteristics of this new voice. petosa is pleased to be in partnership with Voci Armoniche to bring this pioneering concept to market - now available in select petosa models.
Ultra high-end professional voice, offering the formal and acoustic contents of the best Italian artisan tradition. A profile offering excellent acoustic potential, versatility and intensity, balance and definition in the harmonic fullness of the timbre. Hand riveting, very high precision between tongue and plate; tongues worked to perfection. Impeccable aesthetic and formal care, which concerns the whole item, from the shape of the rivet head with the radial facets to the hand polishing of the duralumin plate surface.
TIPO A MANO
High-end professional voice; Tipo a Mano means "made like hand". The Tipo a Mano reed was originally conceived by Luigi Antonelli in 1952. Petosa has continued to utilize Antonelli Tipo a Mano reeds exclusively since their inception. The unmistakable "classic" voice with excellent acoustic potential and tonal balance. Similar but different to the handmade reed with its own acoustic characteristics of great value. The reed finish is crafted, shaped and filed by hand with the same precision artisanship as Antonelli handmade reeds beginning with a sheet of swedish blue steel rather than a ribbon.
