The double bass stands around 180 cm ( six feet ) from scroll to endpin, and is typically constructed from several types of wood, including maple for the back, spruce for the top, and ebony for the fingerboard.

At the base of the double bass is a metal rod with a spiked end called the endpin, which rests on the floor.

The instrument height is set by adjusting the endpin such that the player can reach the desired playing zones of the strings with bow or plucking hand.

Bassists who stand and bow sometimes set the endpin by aligning the first finger in either first or half position with eye level, although there is little standardization in this regard.

The instrument is twice as long, curves around on itself twice, and, due to its weight and shape, is supported by an endpin rather than a seat strap.

The tailpiece is typically made out of bone, and secured to the carved projecting " endpin " by stout steel wire.

The instrument is held vertically and is supported by the player's legs ( rather than with an endpin as in the modern cello ).

The endpin or spike is the component of a cello or double bass that makes contact with the floor to support the instrument's weight.

One type of endpin stopper is placed between the endpin and the floor to add surface area and enhance friction, and stands alone.

Since in this case the distance from the stopper to the chair is usually fixed, such stoppers typically have a line of dents running down the plank, allowing the instrument's angle to be adjusted by placing the endpin in a different dent.

However, the sharper the endpin, the more likely it is to go through the standard rubber tip.

Generally, endpins are parallel to the long axis of the instrument, but some cellists fit their instruments with a Tortelier-style endpin, which angles more towards the floor, improving mobility at the expense of stability.

The extended endpin of a cello, a black rubber cap and accompanying screw lie next to it

Left-hand pressure on a cello fingerboard, acting against the fulcrum of the player's chest and / or knees, may cause the endpin to slip forward on the floor.

A violone or " great bass viol "; painting by Sir Peter Lely, Dutch-born English Baroque era painter, c. 1640, showing a large bass instrument of da braccio corpus form, but with a very wide fingerboard, played with underhand bow grip, and without an endpin

The endpin also serves to hold the bottom of the instrument to a strap or belt worn by the player.

David Popper was one of the last great cellists who did not use an endpin.

Most electric cellos feature a traditional endpin and knee supports, but some are supported in other ways, such as by an elongated pin for playing in the standing position, a tripod stand, strap, or strap system that allows mobility while playing the instrument.

The endpin also may have notches cut in it, allowing it to have extra holding strength at these points.

To prevent this slippage, objects known as " endpin stoppers ", " pinstops ", " donuts ", " endpin anchors ", " endpin holders ", " spike holders " or " rock stops " are sometimes used.

A different sort of endpin stopper uses the musician's chair as an anchor.

Your suggested solution, it seems to me, is grossly oversimplified and is inconsistent with your generally realistic attitude toward, and endorsement of, sound planning.

It would challenge sharply not the cult of the motor car itself but some of its ancillary beliefs and practices -- for instance, the doctrine that the fulfillment of life consists in proceeding from hither to yon, not for any advantage to be gained by arrival but merely to avoid the cardinal sin of stasis, or, as it is generally termed, staying put.

It is generally conceded that the Formosan air force is the best by far in Asia, and the army the best trained.

The total adverse impact of disease, insects, fire, weather, destructive animals, and other forces on the uses and values of forest resources is not generally recognized.

Any alteration of one of these factors is distortion, although we generally use that word only for effects so pronounced that they can be stated quantitatively on the basis of standard tests.

Now, the machine has been improved to a point where it is generally more economical than oil heat at temperatures down to 15 degrees.

It is generally an inaccurate method of rating, for the horsepower is that of the compressor motor, and many other components beside it determine how much cooling you'll get.

Above this point there is no generally used parallel ladder.

Advances in equipment and fabrication techniques give the sign or display manufacturer an extremely wide choice of production techniques, ranging from injection molding for intricate, smaller-size, mass-production signs ( generally 5000 units is the minimum ) to vacuum and pressure forming for larger signs of limited runs.

Brown ( 1959 ) has reviewed generally the various methods of assaying TSH, and the reader is referred to her paper for further information on the subject.

The great majority of present-day linguists fall into one or more of a number of overlapping types: those who are convinced that tone cannot be analysed, those who are personally scared of tone and tone languages generally, those who are convinced that tone is merely an unnecessary marginal feature in those languages where it occurs, those who have no idea how to proceed with tone analysis, those who take a simplistic view of the whole matter.

My answer is in the negative because I believe that total capital demands during the Sixties will continue to press against available supplies, and interest rates will generally tend to be firm at high levels.

In general, it appears that trustees and board members attempt to represent the public interest in their administration of educational policy, and this is made easier by the fact that the dominant values of the society are middle-class values, which are generally thought to be valid for the entire society.

In his analysis, however, he touches upon but fails to explore an idea, generally neglected in discussions of the book, which I believe is central to its art -- the importance of human hands as a recurring feature of the narrative.

The respectability which money confers implies a different etiquette, and, upon taking up the life of a London gentleman, Pip must learn from Herbert Pocket that `` the spoon is not generally used over-hand, but under ''.

Because of undesirable flavors, odors, colors, and generally low palatability associated with radiation treatment of this magnitude, the inactivation of enzymes is best accomplished prior to irradiation by the conventional heat-processing methods of blanching.

The polyester urethane foam is generally produced with adipic acid polyesters ; ;

An electrostatic system suffers generally from image plane curvature leading to defocusing in the peripheral image region if a flat viewing screen ( or interstage coupler ) is utilized, while a magnetic system requires accurate adjustment of the solenoid, which is heavy and bulky.

The packing efficiency, F.R., of fiber plates did not receive much attention in the literature, probably as it is high for the larger fibers generally used, until rather recently.

Intermarriage, which is generally regarded as a threat to Jewish survival, was regarded not with horror or apprehension but with a kind of mild, clinical disapproval.
