What is a word starting with O that has to do with conductor?

Answer 1

Sounds like an "orchestra" - which is led by a conductor.

Other possibilities would be:

Oboe - and instrument in the orchestra led by the conductor

Overture - an orchestral composition forming the prelude or introduction to an Opera, oratorio, etc. - which is led by a conductor

Opera - the music for which is led by a conductor

Oratorio - the music of which is led by a conductor

Octave - An interval covering eight diatonic scale degrees - which is used in the music the conductor conducts

Octet - a group of eight instruments or singers - which may be led by a conductor

Orchestration - the art of arranging, writing or scoring music for an orchestra - which many conductors are also adept at but even if they are not, the music they lead is probably going to be the product of orchestration

Opus - "Work". With a number, used to show the order in which the works by a given composer were written or published. Opus numbers are most often used for composers who catalogued their own works - which a conductor leads a group of musicians to perform

Of course you could also think of an electrical conductor - in which case the best word would probably be "ohm" or "ohms". An ohm is a measure of electrical resistance - the reciprocal of conductivity of a conductor.

Also:

ohmmeter - which is used for measuring resistance (the reciprocal of conductivity)

ohmage - Electrical resistance expressed in ohms

overload - what happens to a circuit if it's not a good enough conductor
