The big scores by the two masters of film music such as Psycho, Vertigo and Star Trek are well-known, but less well-known but perhaps even more brilliant are the TV scores done by these two composers for the original Twilight Zone and Alfred Hitchcock Presents.
You will often hear film music that is a big, full ensemble of all the instruments but which is a mediocre use of all that power. But in these scores, you hear the opposite: tiny ensembles that are used so perfectly and imaginatively that most people don't even realize an orchestra is not playing!
An example I just noticed was the Herrmann score to "Living Doll" of the Twilight Zone. It is scored for three instruments only: Bass clarinet, Harp and Celesta. It is fantastic, masterful use of that unique combination from a purely orchestrational standpoint, but also is perfect for the film.
Another one is the score by Goldsmith to The Invaders of the Twilight Zone. It is for strings, with a prominent solo violin.
Yet another is the Herrmann score for "Walking Distance" which is one of his best wistful, romantic string compositions, so good it was recently re-recorded for a CD. How many TV show complete scores - not just theme songs - have had that done for them? Probably not one other.
What impresses me about these is how they use such small forces to create such a huge effect. The artistry of the composition is what makes them big, not hiring more players. Also, with these short "Chamber Music" scores you can hear far more clearly what is being done by the composer than in a special effects-explosion-laden blockbuster. The real art of film music is contained in these and can be learned from these beautiful gems far more than going to the theater and having your ears assaulted by noise.
