My friend Marion Harrington has published the second in a series of articles on the colossal subject of interpretation on her blog.
She offers clear and sensible advice to all musicians, and encourages fearlessness (with proper study) in tackling the daunting task of creating a personal style.
She also suggests that musicians need to lower their barriers to sharing "practice" recordings to enhance fresh thinking about our own ideas.
Along with mastering technical difficulties, it is vitally important at that you come to your own conclusions about mood, emotional content, dynamics, phrasing, articulation and tone early on.
...I’d like to see more open honest audio sharing – aside from the usual big label manufactured “perfect” album or track releases – between musicians, without the fear of unconstructive criticism. We all need regular feedback and evaluation to grow. Recordings – including practice sessions, “work in progress” and performances of whatever standard – inspire, motivate and challenge or validate our own ideas. A few musicians have been brave enough to “go public” but not enough, particularly the “names”. Why do you think the status quo is like this?
