Pedro Maffia was an excellent musician and a refined artist, and the creator of a totally different concept about the playing and the handling of bandoneon. Technique and style were the foundations upon which he built his personal style. He created a way of expressing tango, a characteristic sound of refined musicality and even a physical attitude about the possession of the instrument, leaving behind the spectacular folds of the instrument, which transmitted a certain aggressive stridence. Maffia gave bandoneon playing a new style, which would be followed by all bandoneon players after him. He also gave his sextet a characteristic and very personal mark, of a more mellow sound than De Caro’s orchestra, with a tendency to chained sounds and always included in an equally evolved harmonic criterion. When his orchestra was asked to make some recordings, he incorporated a violoncello to it, which gave the group a velveteen sonority that fits perfectly with the temperamental tessitura of his bandoneon. Maffia, who always counted with the support of the audience that was addicted to qualified and popular musical manifestations, followed an unaltered artistic orientation about the quality of his versions and the selection of his collaborators.
