One of the biggest weaknesses that present in soft dynamic range staccato scales, is a lack of projection. Students often snuff out notes, play them in a whisper without a tenacious spring UP character, or a necessary rebound effect from note to note. Instead, they become inhibited and constrained. Yet even at the Forte level, their staccato rendered scales may lack definition, animation, adequate SPACING, and overall shape/direction.
In an attempt to remediate lackluster scales that transition from smooth and connected legato to staccato, particularly in the soft cosmos, I suggest mental images to frame the sound, while also demonstrating the springing UP character of these detached notes to create an ear-catching environment.
Two Sample Lesson Excerpts:
C-sharp minor (Melodic form)
In the second example, the student also worked on intensification of the Melodic minor ascent (staccato), in contrast to a relaxed descent. (i.e. Naturalization of the C-sharp minor scale) Finally, she rendered the C-sharp minor Arpeggio, refining a Forte/Piano staccato transition in triplets.
