Guitar picks are instruments that are used to pluck, strum, pick, and control the tone of a guitar. A guitar pick is basically a long, narrow plectrum often made of one solid material, such as rubber, plastic, felt, wood, tortoiseshell, stone, or other material. They're usually shaped in an isosceles pattern with both the two equally rounded corners and the third rounded one slightly less rounded.
Some Spotify Guitar Picks are fretted and have a flat back; others are fretted and have a round back. They're sometimes sold as single-sided plectrums or double-sided plectrums and can be purchased in different sizes. Guitar picks are available in several different types. The most popular are flat-backed plectrums, which provide a sharp, thin sound; plastic-cased plectrums, which have a hollow sound; and wood guitar picks, which have a hollow sound and are more tonally sensitive than their plastic counterparts. They're also used in calligraphy, because they give a smoother, mellower tone than the metal and slate versions.
While there are many types of guitar picks, the most common ones are flat-backed and rounded. A flat back guitar pick allows the guitarist to hit the strings at a precise angle, producing rich harmonic tones; rounded guitar picks allow the guitarist to hit the strings at an angle that produces a deeper, fuller sound. It's important to learn how to use each type correctly, since using the wrong technique can result in injury. As a beginner, you'll probably want to start out with a flat-back guitar pick so that you can get a feel for what you're doing and build your technique skills gradually.
Another essential tool in your guitar picks arsenal is the nylon pick. Similar to the flat guitar picks, the nylon pick offers a wide variety of sounds, including a strummed nylon string sound or a picked nylon string sound. The main difference between nylon picks and plastic picks is the texture of the plastic, which allows it to be pressed against the guitar strings without creating too much friction or pulling on the strings. Nylon guitar picks are usually a bit wider than plastic picks, and they're often used for lead playing, because they give a smoother tone than their heavier cousins.
A less expensive alternative to nylon guitar picks is the celluloid custom guitar picks. Made from molded fiberglass, celluloid picks are similar to nylon picks in their thickness and pliable structure. Like nylon, celluloid picks can be shaped flat or curved. The main difference is that it requires no oil to keep its shape. On the downside, they don't last as long as the nylon pick because of the materials used to construct them, which are more susceptible to damage than nylon. Also, unlike the celluloid version, it cannot be pressed against the guitar strings like the nylon pick.
One other option for your picks is the metal shaped picks, which come in a number of shapes and sizes. These picks are usually shaped like an oar, with either rounded or pointed ends. Metal picks give a warmer tone than their plastic counterparts, because they have a nice round width that can Nestle the finger and allow for easy control of the stroke. They also have slightly larger gaps between their grains, making it easier to distinguish individual grains.
