CECILIA / ANDREA Rosin CECILIA Rosin / ANDREA Rosin Label 2020

Peter Bahng has been making his rosins in New York since 2009, although his rosin formulas were developed while he was still studying violin at The Cleveland Institue. Over 200,000 rosins have been made by Peter since then, and to this day, each and every rosin is still hand crafted by Peter. The making process has been refined and improved during this time. His rosins have become known and trusted worldwide for their excellent playing properties. Simply put, musicians can rely on his rosins to create a great sound and to allow artistic freedom. From the beginning of 2020, Peter changed the name of his rosins from ANDREA to CECILIA. The CECILIA rosin collection offers the original, unchanged and popular Solo rosin together with the A Piacere and Sanctus models. A new addition to the professional line-up called Signature Formula has been developed as the flagship of the CECILIA rosin collection. As with his other rosins, this new rosin has received acceptance and accolades from professional musicians around the world.

Read how Peter developed his rosins from a young age and created the first rosins under the names of TARTINI, then ANDREA and now CECILIA.

ANDREA rosin colours

CiA ANDREA / CECILIA Rosin Colours

Colour of rosin - rosins come in different colours. Colours range from bright yellow to amber to dark brown and sometimes green. Most string players think that darker rosins are softer and stickier which suits cold and dry climate conditions, with light coloured rosins being the opposite. This can sometimes be true. However, this is not the case for ANDREA rosins or some other rosins on the market because they are formulated with other ingredients that have naturally different colours. There are also some rosin makers who add various colour pigments to their rosins.

The very light colour in the outer ring of the ANDREA “Sanctus” is from the hydrogenation process.

"I love trying new things, to stay in touch with innovators and follow developments. But when it comes to rosin, I always, always come back to Andrea "A Piacere". The only rosin that effects my sound instantly, rich in overtones for that extra golden tone quality we cellists look for. Very responsive in articulation while at the same time you feel the bow 'sink' into the strings. What a pleasure to play! "
Karel Bredenhorst - and

CiA ANDREA / CECILIA rosin CLP Labelling 2017

In June 2017 the EU labelling regulations (ECHA/REACH) changed. This meant that because there is no small item exemption any more, all rosins that contain rosin / colophony ought to be labelled as such with the relevant safety warning for colophony. ANDREA rosin most definitely contains a wonderful blend of rosins together with other special ingredients. So you will see that ANDREA rosin now wears a small multilanguage booklet label.

CiA ANDREA Kolophonium

CiA ANDREA Kolophonium gibt es nun auch wieder in Grossbritannien sowie im restlichen Europa. Jedes Stück wird in den USA von Hand hergestellt. Es wird aus einem Gemisch von sorgfältigste ausgewählten Materialien und Inhaltsstoffen unter der Anleitung des professionellen New Yorker Violinisten Peter Bahng (Sang-Wook) hergestellt. Lesen Sie HIER die Geschichte von Peter's Vater Andrea Bang, dem Erfinder des Kolophoniums, einem ebenfalls berühmtenViolinisten. Vielleicht erinnern Sie sich, dass ANDREA Rosin vor einigen Jahren von Andrea Bhang unter dem Namen „Tartini“ hergestellt wurde (nicht zu verwechseln mit „New Tartini“, welches ein anderes Produkt ist).

Das neue Kolophonium von Andrea Rosin ist in einem Polystyrolkästchen mit einem Durchmesser von ca. 5 cm und einer Höhe von 2,5 cm verpackt. Das Kolophonium selbst hat einen Durchmesser von ca. 4 cm und eine Höhe von 1,5 cm. Es wird überwiegend von professionellen Musikern gekauft und benutzt. Wegen des Klanges, den es hervorzaubert und seiner sparsamen Anwendung ist es jeden Cent wert. Wenn Sie Ihren Bogen drei bis viermal darüber streichen, reicht das vollkommen aus. Das sind vielleicht 5 Cent pro Woche für weit über ein Jahr ...

CiA A PIACERE ROSIN: Das „A Piacere Rosin“ war früher bekannt als „Tartini Green Rosin“.

CiA SOLO ROSIN: Es erzeugt einen klaren, reinen und tragfähigen Klang, den Solisten lieben. Das ist keineswegs nur ein Marketingslogan - das Kolophonium ist wirklich phantastisch! („Solo Rosin“ war früher unter dem Namen „Paganini“ für Violine, „David“ für Viola und „Casals“ für Cello bekannt).

CiA ORCHESTRA ROSIN: Es erzeugt einen weicheren Klang, der sehr gut für das Spiel im Orchester beziehungsweise für Tonaufnahmen geeignet ist. Der Klang ist wesentlich kontrollierter. Das „Orchestra Rosin“ war früher bekannt als „Symphony Rosin“. (Außerdem als „Vitali“ für Violine, „Vienna“ für Viola und „Toscanini“ für Cello).
