It is the tendency of moving objects to continue moving in a straight line. Together, gravity and inertia are responsible for the creation of two major tidal bulges on the Earth (Ross, D.A., 1995).ravity, Inertia, and the Two Bulges.

A symphony is a large, multi-movement work for orchestra. It calls for instruments from all four sections (winds, strings, percussion, and brass) and explores a complete range of melody, harmony, rhythm, dynamics, and timbre. That seems like a basic definition, but even that already has a number of exceptions. The symphony really came into existence with the Classical period and Haydn.

Likewise, every philharmonic is a symphony, but not every symphony is a philharmonic. Okay, letâs take a breath. Orchestra is a broad term for any ensemble featuring a hefty lineup of strings.
