This is a brief introduction, less than a minute, to a larger piece.
Actually there are "Seven Ages" of Man, each one represented by a different set of instruments. Each time the "age of man theme," or motif, is played, there is different emphasis, tonal range, slightly altered melody, and greatly altered timbre and mood. Each "age" lasts only about seven seconds. In sequence, each age is represented by:
1. Two Large Glockenspiels
2. Violins, legato and pizzicato.
3. Brass. Horns, Trombones, and Tuba.
4. Woodwinds. Oboe, English horn and bassoon.
5. Flute, triangles, woodblock and tam-tam.
Here is the tam-tam:
And the wood block:
6. A large open concert grand piano.
7. Large string section.
