Using only two lines, writing out rhythms, patterns, exercises, etc. has been done more often than not (the Chapin book, for example). Two lines are a convenient way to communicate rhythms and coordination patterns.
Two Lines Wide
A wide-spaced double line has been used by several authors. Specialized stationery often helps a student to learn easier. Extra lines can be distracting...small note heads may not be large enough or clear enough to help. Purchasing the download kit gives you notation lines to use as often as you wish (standard music paper also included).
