[Complete Play-Along tracks sold separately at the author's website - see below]Internalizing 2 against 3 is every musician's wish.

In this book, you will find 56 exercises in both, scalar and rhythmic notation, that will take you from the simple pattern of - half note triplet against whole notes - into the complex -syncopated 16th note triplets against syncopated 16th notes, hoping that along the way, this will help you achieve effortless sensitivity to swing and groove. Included with the eBook (sold separately) are play-along tracks of all 56 patterns with stereo separation so you can "hear" each pattern and practice against any line you wish.* Play-along tracks are available for download at www.tarekyamani.com/dupletriple* eBook (pdf version) + play-along tracks can also be purchased as a bundle from the author's website at www.tarekyamani.com/dupletriple
