Is there any school of thought that promotes playing ambidextrously?
Can you recommend any software based studies that follow the left-handed method or any of the things that you described in your reply at the beginners level?
There are also many pieces written for Left Hand alone, the most notable being Prokofiev's Fourth Concerto, Ravel's Concerto for Left Hand, Britten's Diversions for Left Hand and Orchestra etc. Ed
Ed suggested: Nice beginner's pieces Ed!
If what you want is for your left hand to be able to do the same sort of patterns of the right hand (and therefore most pieces of the melody/accompaniment format are unsuitable), you will have to look into polyphonic music. At the beginner-intermediate level, have a look at these 3 Konnemann's compilations:1. Early dances (Ed. Agnes Lakos)2. Introduction to Polyphonic playing (Ed. Agnes Lakos)3. The Baroque pianist (P. Vappavuori & H. Hynninen)Slightly more difficult are:4. J. S. Bach's - 18 Little preludesIf the pieces in these collections are too easy, then go up a notch and try:5. J. S. Bach - Two voice inventions.Which can be followed up by:6. J. S. Bach - Three voice inventions.From there, anything by J.S. Bach (Preludes & fugues, Partitas, French & English suites, etc.) will give you not only ambidexterity as well as hand and finger independence.Also, have a look at this related thread:https://www.pianoforum.net/cgi-bin/yabb/YaBB.cgi?board=stud;action=display;num=1067980504Finally, most people experience problems with the left hand because they do not have the habit of using it in an integrated, co-ordinated way in their daily lives. Consider the way you cut a steak with knife and fork. Most people (yes, I ask these questions from people ) tell me they do it with their hands. But actually they do it with their arms. When it comes to piano playing, beginners will be all right on the right hand since they are using the whole arm in a coordinated way to play. But the left hand is used only form the hand down. Since people are not used to total left side co-ordination, they do not use it when playing the piano.There are two ways of fixing this. First, start to use your left hand - or should I say - the left side a lot in daily life (e.g., when brushing teeth, when opening doors, when washing dishes, when moving stuff - you get the idea). Second get an inverted piano (they are expensive, but they exist!). these pianos are built so that the treble is left and the bass is right. This means that you can play a piece with your left hand playing the treble part and the right hand playing the bass part. The perfect solution, even if you do not hate Bach!Best wishes,Bernhard.

I can only think of one reasonably easy study off the top of my head but if you own Burgmuller's book of progressive studies, there's one in it called Ballade and there is a lot of left hand melody in it. I think there are other studies in there which use the left hand for melody too.This book is really widely available.
