Yes it is a sin.  It will destroy your interpretation, and corrupt your soul for all of eternity.  When you die you will be judged unfit to play on the treble clef, and you will be condemned to forever play only on the bass clef.  It is a sin to even think of what you are proposing here.  There mere fact that you have even thought about this is the same as having done it.  So you are doomed forever with no hope of repentance.

Also the fact that you have lustfully eaten from the fruit of the Inventions before having patiently reaped the wisdom from the garden of WTC is so contemptible that the penalty for that is unspeakable. 

Sorry, but that's just the way things are.

i'm still laughing a bit from leucippus response.  the harpsichord gave very little ability to shade meanings as the piano does.  if you see four of five levels of dynamics - there's something shady going on, imo.  but, according to romantic interpretations - anything goes.
i think if more students were given the opportunity to play on a harpsichord once or twice - they would see and hear better in terms of what they might want to imitate.  i say, might, because everyone is different.

i personally prefer to hear only the basic two.  forte and piano.  the reason i say this - is that there are many different variations of playing using only those two dynamics, and, in my opinion, is very effective.  reminiscent of the early fortepiano.

or, you can choose to play only one, mp or mf.  the additional voices that come in give you the textured loudness rather than dynamics through the touch or pedal.  also, the speeding up of rhythms (say you start with slower notes and move toward sixteenths) gives an impression, together with more voices, of a loudness vs softness.

agreed, totally!

I am a sinner and I have no moral values.  I can't wait to learn the Bach Inventions so that I may pour my heart out engorging them with erotic romantic dynamics.

I have every intention of playing all 30 of them like this and recording them on a CD with a front cover of me in an open black vest that reveal the hairiness of my romantic sensuous chest.  I'll call it, "The Insidious Immodest Inventions of Bach"

It’ll be a big hit, you wait and see. 

hmm.  i never really thought of cello and violin.  i suppose you are right.  carry on, leucippus.  i sort of want to buy that cd already.

Are three-part inventions graded easier than WTC pieces? The reason I ask is because as a beginner, my teacher recently assigned WTC Prelude I to me. Is it just this specific Prelude I that is particularly easy - I have not tried the others yet, and certainly not the Fugue  . Anyway, if three-part inventions are easier, I'm wondering why I skipped over them?

Anyone?

Bach himself ordered his works for study as such:

1. The little book of Anna Magdalena Bach
2. The little book of W.F. Bach
3. Two-voice inventions
4. Three-voice inventions
5. French and English Suites
6. Partitas
7. Well-Tempered Clavier
8. Goldberg Variations, Italian Concerto, Chromatic Fantasy and Fugue

I assume he referred primarily to the fugues of the Well-Tempered Clavier in this progression.  (Of course, however, some preludes can be quite tricky.)  Also, remember that a good teacher does not waste time - you may not have needed the three-part inventions.

Best,
Michael

I'm thinking like maestoso.  I don't find the Inventions easy at all because I have yet to learn hand-independence.

I've been searching for more pieces similar to the 12 Köhler studies.  Pieces that slowly meld your hands together with progressive results.  I've actually been thinking about writing up my own etudes for this purpose.
