Suites are often made up of contrasting movements or sections, each with its own unique character or theme. **

A symphonic poem is a single-movement orchestral work that is typically inspired by a literary or visual source, and it aims to convey a specific story, idea, or emotion. It is often programmatic in nature, meaning it has a narrative or descriptive element.

A gas heater uses a spark to ignite the gas and create a flame. Once the gas is ignited, it continues to burn and produce heat without the need for a continuous spark. Therefore, after the initial spark, there is no need for it to remain lit as long as the gas is burning. This is why you may only see a spark when the gas heater is turned on, and not a continuous flame. **
