Concone is best recognized throughout the world for his didactic works for the voice. Among his rich and extremely varied production, the 50 Lezioni op. 9 is particularly outstanding, a most successful publication with numerous reprint editions. There isindeed abundance of "simple, expansive melodies with a regular rhythmic pulse" in these Lezioni, thus allowing the medium of the voice to develop gradually, without forcing. The piano part is sober and striking. Finally, the composer provided numerous dynamic indications and strove to maintain rhythmic variety throughout. Introduction in Italian and English. Beginners to intermediate. 2 CDs of piano accompaniments. --the publisher
