Q: Music for the triangle is written on the percussion staff, often with triangular shaped notes, but is sometimes written with regular music notes.  Triangles have an indefinite pitch, the notes will appear on the same line often as some of the other such instruments, such as bass drum and cymbal. The same note values apply for the triangle, i.e. a whole note, half note and quarter note, eighth notes, etc. Playing the triangle gets harder the shorter the notes are, so this is a really important skill to master. Graces notes are notes played in a specific rhythm before the first note in a musical measure. Playing grace notes on a triangle is easier if you suspend the triangle on a music stand with clips and play with two matched beaters.
A: Learn to read triangle notes. Practice grace notes.

Q: Let a little time go by before you apologize. This will allow both of you to cool off some while giving you time to think about how to make the best apology that you can. Try to get a sense of whether the other person is upset still. Although you will probably recognize it when you see it, expressions of anger may involve clenching of the face or fists, yelling, throwing objects, etc. One surefire way to seem insincere is if you do not take the time to apologize face-to-face after your dispute. In addition, much of the information you convey about how you feel is done through your nonverbal communication channels (i.e., through your body). The only time it is acceptable to not apologize in person is if it would be a great inconvenience to either person to have to meet. For example, if who you wish to apologize to lives very far away, it is not practical to meet in person. There's a good chance that after a dispute, you will regret some of the things that you said or did. Be sure to say what each of this is; don't leave anything out. Be sure to include how your actions impacted the person you are apologizing to so this person knows that you know how he felt. If you want to make sure you don't leave anything out, it can be helpful to write down on paper what you regret so that you can study it before you make your apology and/or refer to it in the moment. After a dispute, it is important to state your regrets sincerely. You can express sincerity with your body language. As you state your regrets, make steady eye contact with whomever you were disputing with. In addition, try to maintain a relaxed body posture, while leaning slightly towards this person.  Above all though, make sure your words are sincere. You can do this by only saying what you mean.
A: Wait for the dispute to die down. Apologize in person. Say what you regret. Be sincere.

Q: You may be asked to demonstrate a particular scientific principle or theory. If this is the case, your conclusion should reflect that.  If it’s not clear in your conclusion what you learned from the lab, start off by writing, “In this lab, I learned…” This will give the reader a heads up that you will be describing exactly what you learned. Add details about what you learned and how you learned it. Adding dimension to your learning outcomes will convince your reader that you did, in fact, learn from the lab. Give specifics about how you learned that molecules will act in a particular environment, for example. Describe how what you learned in the lab could be applied to a future experiment. Your teacher may have listed certain questions in the assignment that need to be answered. On a new line, write the question in italics. On the next line, write the answer to the question in regular text. The introduction to your lab report should have stated certain objectives that you hoped to achieve with this experiment. Revisit these objectives in the conclusion to make sure that you are addressing them sufficiently. If your experiment did not achieve the objectives, explain or speculate why not.
A: Describe what you learned in the lab. Answer specific questions given in the assignment. Explain whether you achieved the experiment’s objectives.

Q: If you're just starting out with the instrument, there's no need to spend an excessive amount of money on a violin, but like most instruments, the quality of the violin generally rises as the price goes up. Expect to spend a few hundred dollars on a decent beginner's violin.  Buy full size or 4/4, if you're an adult. The violin is a small instrument, but there are specially designed smaller sizes available. These are generally only intended for younger children, so be sure the violin you're buying is full size unless you're very small. You can ask the shop for a recommendation if you aren't sure.  You can also ask the shop to measure your arm length to see what size violin you need. When holding the violin in the playing position, straighten your left arm and the tops of your fingertips should be near the top the violin scroll. If your arm is way past the top, the violin is too small. Buy from a reputable seller. Music stores stake their reputations on selling solid instruments that are free of obvious flaws and damage. As a beginner, you won't be able to coax a very pleasant sound from your instrument for some time, so flaws in privately sold violins might not be apparent to you until it is far too late to complain. Only buy from a store or individual you can trust. Unless you have purchased the instrument only, your violin outfit should come with a violin with four strings, a bow, and a carrying case and most of the time a chin rest and rosin for your bow. In most cases, the person who sells you the violin will be happy to string it for you, which has the added bonus of double-checking to be sure the tuning pegs (the knobs at the scroll, or top, of the violin) are properly fit to the scroll. A hard case is important because violins are such delicate instruments.  Strings come in three basic varieties: gut, which is expensive and difficult to take care of, but which offers a complex range of sound; steel, which is loud and bright but can sound scratchy, and synthetic, which is smooth, clear, and not as unpredictable as gut. Each type's name refers to the core material around which metal wire is wrapped to create the string. Most beginners should go with synthetic core strings, such as nylon core.  The bow should be new, or newly re-haired. You can check this by looking at the hair of the bow (the fine, white or off-white fibers) and ensuring that the color is uniform and bright along its entire length. The hair of the bow should be a uniform width from end to end. Bows wear down over time. You can get your bow re-haired for a small fee at most music shops. Nearly all violinists use a chin rest, which is a cheap, ergonomic piece of (usually black) plastic that clamps near the base of the violin and allows it to be held securely by your chin. This is usually attached to the violin when the violin is built. Aside from that, be sure you have some rosin (coagulated sap) for your bow, a music stand, and a book of beginner lessons or songs, preferably in a format that will open flat.  Some violinists, especially beginners, also purchase a shoulder rest, which is a violin-width pad that sits on your shoulder underneath the violin and makes it easier to hold. Many people start with a shoulder rest and eventually remove it after a few years. If the violin seems to dig into your shoulder when you play, consider purchasing one. Fiddlers, if they sing while performing, often hold the violin in the crook of an arm while playing, with the butt resting against their shoulder. For them, chin rests and shoulder rests are generally pointless. A tuner is a small device that clips on to the scroll or the pegs of the violin. It is useful for beginners if you are teaching yourself, as it can be used to make sure you are playing the notes correctly. But once you know how to play the notes, the tuner isn't of much use anymore except for tuning the instrument itself. Be sure to take it off before big performances though, as it looks unprofessional.
A:
Buy or rent a violin. Check the accessories. Purchase other items.
