Trombone
The slide on a microscope is typically held in place by a mechanical stage, which has clips or a spring-loaded mechanism to secure the slide into position. Some microscopes also have a stage stop to prevent the slide from moving too far in any direction.
Magnifying / Microscope lens
A microscope is a science instrument that uses slides. Slides are small rectangular pieces of glass on which specimens are placed for viewing under the microscope. The slide holds the specimen in place and allows light to pass through for magnification and observation.
A structure refers to the arrangement of elements within a system, while a mechanism describes the process or series of steps that lead to a specific outcome. Essentially, structure is the form, whereas mechanism is the function or operation. In other words, structure is the framework, while mechanism is the way things work within that framework.
A definite pitched instrument produces sound at fixed frequencies that are constant at each position or setting. Example: a piano is a definite pitched instrament. When you press Middle C on the Keyboard the same tone occurs every time. "Digital sound is another example" Where a indefinate pitched instrument is linear or analog in that there is no specific separation between notes. Trombones are a great example, because the slide allows the instrument to not only play a clear precise note such a Middle C, you can plan an near infinate numbers of tones between Middle C and C sharp by minute changes in the position of the slide. Another way to look at it is, stairs versus ramps. You go up and down stair in measured amounts, no stopping between steps. A ramp has infinite points you can stop and start from. Hope this helps.
A brass instrument with a slide to make notes
On piano and other keyed instruments, this is called a glissando.
That would be the trombone, as it changes notes by use of a slide rather than valves.
The trombone has a slide that can be moved to change the pitch of notes rather than valves or keys that lengthen the tubing to change the pitch of notes like other brass instruments. And there are a lot more than 3 other brass instruments.
The trombone key is used to change the pitch of the instrument by extending or retracting the slide, which alters the length of the tubing and produces different notes.
You can either press down or release valves , or you can adjust the slide on a trombone . You also can adjust the 'airspeed' to change the pitch without changing the valves or slide
A tuning slide is a movable part on a musical instrument, typically found on brass instruments like trumpets or trombones. It is used to adjust the length of the instrument, which changes the pitch of the notes produced. By moving the tuning slide in or out, musicians can fine-tune the instrument to play in tune with other instruments or to adjust for temperature or humidity changes.
Unlike the rest of the brass family, trombones change notes by moving a slide instead of using valves.
The sliding mechanism joins the phone to the keyboard. The mechanism causes the keyboard to slide out from underneath the phone.
Slides on any valved brass instrument can be adjusted for tuning, but they don't move enough to completely change notes.
A trombone is an instrument that is played moving a slide back and forth.
Brass instruments have a brassy timbre due to the size of the bore (the hole), and how much emphasis is being put in to playing the instrument in order to generate the noise quality from the instrument.
