The meanings of both numbers and letters vary from manufacturer to manufacturer, and some sticks are not described using this system at all, just being known as Smooth Jazz (typically a 7N or 9N) or Speed Rock (typically a 2B or 3B) for example. Many famous drummers endorse sticks made to their particular preference and sold under their signature. Besides drumsticks, drummers will also use brushes and rutes in jazz and similar softer music. More rarely, other beaters such as cartwheel mallets (known to kit drummers as "soft sticks") may be used. It is not uncommon for rock drummers to use the "wrong" (butt) end of a stick for a heavier sound; some makers produce tipless sticks with two butt ends.
Strumming, usually with finger nails, is a common technique on acoustic guitar, but it is not a commonly used technique for bass. However, notable examples are Stanley Clarke's bass playing on the introduction to "School Days", on the album of the same name, and Lemmy who was noted for his use of chords, often playing the bass like a rhythm guitar.
At the heart of most stages is the acoustic drum set. It's made up of tom-toms, snares, at least one bass drum and an array of cymbals. You'll find all of those here, and there are choices for anyone. If you're just getting started as a drummer, you can get up and running fast with a shell pack or drum kit that gives you everything at once. Or, if you prefer, you can pick individual pieces ""a la carte"" to customize your own set from the ground up. The choice is yours.
In Canada, the Humber College Institute of Technology & Advanced Learning offers an Advanced Diploma (a three-year program) in jazz and commercial music. The program accepts performers who play bass, guitar, keyboard, drums, melody instruments (e.g., saxophone, flute, violin) and who sing. Students get private lessons and perform in 40 student ensembles.
A player can use the fretting hand to change a sounded note, either by fully muting it after plucking it, or by partially muting it near the bridge to reduce volume, or make the note fade faster. The fretting hand often mutes strings that are not being played to stop sympathetic vibrations, particularly when the player wants a "dry" or "focused" sound. On the other hand, the sympathetic resonance of harmonically related strings are sometimes desirable. In these cases, a bassist can fret harmonically related notes. For example, while fretting a sustained "F" (on the third fret of the "D" string), underneath an F major chord being played by a piano player, a bassist might hold down the "C" and low "F" below this note so their harmonics sound sympathetically.
Just like the acoustic instruments they're derived from, digital pianos come in different sizes. They also offer dozens of options for your perusal, so you can weigh all kinds of factors to find the right model for you. For instance, if you're looking to pack a lot of piano into as small a space as possible, consider instruments such as the Williams Allegro 88-Key Digital Piano or the Casio CDP-120. These are fairly compact pianos, but that doesn't limit the breadth of their samples and sound settings.
