If this is some of the best Giacchino has to offer, my point has SO been made. Not with the first piece which is manneristic. It is probably what the director had in mind for the specific scene, every composer would have had to write something similar, and Giacchino seems to have done well with it, but there is no Giacchino in it, and if the job had been done well by someone else, he also would have been invisible so to speak, due to the nature of what was required. The second piece, well the less said the better... It sounded to me like a demo by a current film-music-school graduate trying to bud in a decaying industry, or a piece demonstrating some sound library. At the level of the game Giacchino is playing (Star Trek etc.), I am surprised he is still being offered A-grade films to score (or maybe I'm not so surprised after all).
"Somewhere in Time" is not a technically remarkable piece of music but then again, the argument of this thread has not so much been about technique. I have repeatedly said that almost every big soundtrack these days is nothing more than an orchestration exercise (not a great one every time), and the final product is also very much the efforts of a team of 4-8 people. The point is that "Somewhere in Time" not only complements the film for which it was composed, but in addition a) it is a beautiful memorable melody, and b) it takes seconds for a connoisseur to recognize the composer when heard. I have been talking about how mono-dimensional film music has become these days, when it is nothing, nothing but a characterless carpet (at best - even superfluous and annoying at worst), on which movies today plod as they unfold. It is not one school of many, it is the norm; and it is against this that myself and others voice their despair. This is not about Herrmann alone - he is one great exponent of great film music among many. It is about the systematic elimination of the other dimensions of film scores - ability to stand alone as a concert piece, inspiration, and personal style. I am not comparing the greats of film to the classics, and the examples proffered about Beethoven, Mozart, Liszt and the others are not very good or accurate (if I really must, I will take the time to elucidate and give a short Music History seminar - this is not arrogance, I am probably the worst user of this wonderful Viennese library, I will be the first to sign up for seminars if given). In this respect, I grew up with classical music, not soundtracks, and I have great respect for Barry because he fulfills my requirements for film music greatness, and I do not compare him to Wagner. But I will compare the current batch of film composers to Barry because they are in the same trade. I will say again, producers and directors need to be gently (but constantly) educated in what is good music generally. However, the first that need to be educated in good music are - well... - composers. I would recommend Aaron Copland's "What to listen for in music" as a start, even if it deals with 'serious' music anyway. Then, maybe a few thousand hours of listening to Debussy, Ravel, Strauss, Stravinsky, Prokofiev, Sibelius, Schoenberg, Holst, Orff, Bloch, Respighi, Grofe, Copland (fill your own), as these have influenced great film music directly.
