I first have them clap and COUNT ALOUD, the time signature of a given piece or example--using just quarter notes--4/4 time= 1-2-3-4-1-2-3-4; 3/4=1-2-3-1-2-3; 2/4= 1-2-1-2 etc. etc.Unless they're atypically uncoordinated, they can usually do this, while they tap their foot. I encourage EVERY STUDENT, be it a 7 year-old child or a senior citizen, to tap his/her foot as they play. This helps to internalize meter/pulse, or, to "feel" the beat. *(see note at the end)*At the next lesson, after I'm assured they're secure with clapping/counting the overall rhythm of the piece, I then get them to tap the rhythm played by each hand separately (w/their hands, either on their knees or on the piano above the keys ), as written in their music. They then conclude with tapping the rhythms played by both hands as it appears in their music. This helps them to understand the rhythm, attain the elements of left and right hand independence, without the "worry" of having to decipher which note is "which"/which finger goes "where". *I'M FULLY CONVINCED, that the persnickety practice of REQUIRING the student to sit perfectly still, like a "stiff immobile bump on a log", while chastising him/her for tapping their foot, is an OUT-MODED ULTIMATELY INEFFECTIVE methodology, of yesteryear.It's ineffective because the student then learns to play with fear, and his/her playing reflects the above description! Equally as important is, the student learns NOTHING about internalizing rhythm. If he/she accomplishes it, despite the odds, it's never through THAT so-called "teacher"!
