450 Contemporary Piano Studies in 15 Keys is today's answer to The Well-Tempered Clavier. Drawing on author and composer Charles Austin's extensive lifetime experience as an educator and working musician, this work of 30 pieces in each of 15 keys (five keys in each of three volumes) introduces and explores multiple styles-from Classical to Jazz, Blues, 'Country' and Latin, and is an invaluable resource for piano students and teachers at all levels.
