So when practicing through my scale exercises today, the same idea struck. (And YES, I still practice my scales and daily strive for a bigger range, work on fluency, pitch, upper register ease, and tempo. Some days are definitely easier than others!). For some reason the A# and F# harmonic minor scales were particularly difficult today. Instead of focusing on them thinking "ugh, I gotta get through my scales, " I turned them on their head and brought a playfulness and joy to the practice, singing them, imagining how they should and *could* sound, then created the best scales I could and repeated them until satisfied.
Take the hard stuff and play with it. Find your sense of joy and bring it to your music. You'll be glad you did!
