Keefe's book unites concepts from eighteenth-century music theory, drama, opera, and instrumental music in an illuminating matrix. Closely focused ... this masterly study will expand every reader's appreciation of Mozart's most original genre. NOTES [Andrew Willis] This closely written and thoroughly researched study adds much to our appreciation of the concept of dramatic dialogue in Mozart's mature piano concertos ... What Keefe does offer us is fascinating ... His book is of value in that the higher meaning of these subtle works is often obscure [...] he does much to make it clearer. INTERNATIONAL PIANO A lucid, enthusiastic study, carefully documented, and on the whole wearing lightly the author's hugely impressive learning - he knows the works intimately, and is also very well informed about more general considerations. PETER BRANSCOMBE The book has a great deal to offer ... an impressive accomplishment.
