Cello Rosin and Accessories Overview

ROSIN Rosin provides the bow hair with friction in order to produce a sound when the bow is pulled across the cello strings. Without rosin, the bow will slide across the string and produce a faint whispery sound (or no sound at all). Rosin is generally shaped in round or oblong shapes. A good rosin will enable the bow to grip the string without sounding too rough or coarse. Although most cellists use a dark colored rosin (dark is softer & often more coarse), many cellists have a specific brand they prefer and the color of the rosin can vary. You may want to try several brands until you find the rosin you like best. Visit our Rosin & Sound page for an explanation of how to use rosin.

FINGERBOARD TAPE To assist beginning cellists, some cello teachers use thin strips of colored tape to temporarily mark where students should place their fingers on the cello fingerboard. Teachers often use a variety of different tapes such as pre-cut strips of graphic arts tape (e.g. 1/8"); auto detailing pinstripe tape; commercial instrument tape; or they cut thin strips of tape using masking, painting, vinyl or electrical tape. For pictures and additional fingering assistance, visit our Finger Placement page. Once these tapes are removed, if a sticky residue is left, an instrument cleaner may be used to clean the fingerboard. If the residue is difficult to remove, isopropyl alcohol can carefully be used to clean the fingerboard (do not let the alcohol touch the instrument varnish or it can cause significant damage).

CELLO POLISH/CLEANER To clean your cello, all that is generally needed is a dry, lint-free cloth to wipe rosin from your strings after each playing session. Although polish is rarely necessary, there may be times when you need to clean your cello. Commercial instrument polish is formulated for stringed instruments and can be used to occasionally clean and polish your cello. It’s important to never use commercial furniture polish or water to clean your cello because doing so could damage the varnish and acoustics of the cello.

PEG COMPOUND & PEG DROPS Peg compound can be used to help lubricate sticking pegs (pegs that stick and are difficult to turn). Peg compound will not only lubricate the peg, but will also provide enough friction so the peg will not slip. For slipping pegs, some cellists use either peg compound or another product called peg drops (peg drops, also known as peg grip are used solely for slipping pegs). When using any of these products, do so sparingly because a residue can build up over time (some cellists avoid these products).

Before using peg compound or peg drops, you may want to try the following: If your pegs are slipping on your cello, try pushing the peg in securely while turning the peg firmly to keep it from slipping. If you need a temporary quick fix for slipping or tight pegs, some cello teachers use these tips: for sticking pegs, pull the peg partially out, and rub pencil graphite on the sticking part of the peg. For loose pegs, pull the peg partially out, and rub birthday candle wax on the peg to help it stick (some teachers recommend chalk or rosin to help pegs stick, but these substances are abrasive). If you’re still having problems with your pegs, you may need to take your cello to a cello maker or repair person to replace or reshape the pegs.

MUTES Mutes are devices placed upon the cello bridge to dampen or mute the sound of the cello. Cellists generally use two types of mutes:

1. Mutes for passages of music which call for a muted sound (composers use these muted passages for special effects or a contrast of sound).
2. Practice mutes which significantly reduce the sound of the cello so cellists can practice and not bother others nearby. Heavy metal practice mutes are often able to muffle sounds the most, but you do need to be careful taking metal mutes on and off your bridge to avoid scratching or damaging your cello.

TUNERS & METRONOMES When tuning a cello, most cellists use a tuning fork to tune the open A string, then tune the rest of their strings by ear. Many beginning cellists find it easiest to tune using a digital tuner. Reference pitches are used to tune each open string. Some tuners also use pitch recognition to help the cellist tune their instrument (a needle moves until the note being tuned matches the reference pitch). Visit our Tuning Page for additional tuning suggestions. Some tuners also include metronomes (hybrid products). A metronome can be useful when practicing to help maintain a consistent, steady rhythm, as well as experiment with new tempos.

HUMIDIFIERS Cellists often monitor the humidity in their case and/or room with a hygrometer, and if needed, use a humidifier (excessive dryness or too much moisture can damage musical instruments).
