Q: Training your ear to a certain level may take a very long time. Professional musicians train their entire careers to perfect their musical ear. Even so, perfect pitch is still something of a mystery to scientists and will likely take you much practice for you to attain. Note that achieving perfect pitch may not be possible, but it's also not necessary. Relative pitch is just as useful! If you're a vocalist, this might entail putting on some soft music and singing along with it, or if you're an instrumentalist you might sit down at your instrument after breakfast every day. Hearing the movement of sound among intervals will reinforce these in your mind. These experts can help you fine-tune your technique, but they can also point out areas where your musical ear might be weak. Once you've identified a specific problem, like difficulty hitting high C because it's close to the top of your vocal range, you can practice it until you improve. Once your ear for music improves, you should challenge it often, either at your instrument or with your voice. Use your imagination to recreate sounds that you have heard and try to capture the quality of sound exactly in your head. You might start with a tonal element that's easier to hear, like the root of the chord. Then you can add new tones to it with an instrument, or move vocally from that root to discover the other tones that are a part of the chord progression. This is how you learn to harmonize.
A: Be consistent while learning. Set aside regular time in your schedule to practice. Jam with other musicians. Exercise your ear regularly.

Q: You may be conflicted about whether or not it's a good idea to keep a gun in your home, although it is highly advised for your safety. There are of course safety concerns about keeping weapons in a house with children, but you may also be worried about what will happen to you if you shoot an intruder. Do not worry though, for if you do harm said intruder, it is completely within your rights to harm them if you live in a state with the "Stand Your Ground" law. In most cases, the law will protect you if you shoot an intruder. Even though you will generally be protected by the law for shooting an intruder, you generally must reasonably believe that you are in danger, and you must respond proportionately. This means that if the intruder is threatening you with a piece of fruit, for example, and you know it's a piece of fruit, you could face charges for stabbing or shooting the intruder. In some states, you are required to at least attempt to retreat from the dangerous situation before you can legally respond with force. While the law or statute might be called something else, many states have laws which do not require you to retreat (or attempt to). Instead, you are legally permitted to claim self-defense and respond with force. Even in these states, you aren't allowed to attack without reasonable cause, so be careful. If you can, it helps to research what laws and statutes apply where you live. Generally speaking, if you live in such a state, you're legally permitted to use lethal force upon anyone who unlawfully enters your home, without needing to first determine whether and how much of a threat they pose to you. Again, it's always a good idea to learn what laws apply in your state, and how the specifics vary. If you do feel more secure with guns in your home, it's important that they are securely locked (ideally in a gun safe) and not just hidden. This is all the more important if you have children: even if you think that you've hidden your guns and ammunition where they'll never find it, it is nearly guaranteed that they will discover your hiding places. It's generally recommended that you keep the guns in your home unloaded, and that you store your guns and ammunition separately. You should of course be able to access both quickly in an emergency. Consider storing them in your safe room, but be sure to keep the keys to both where children cannot find them. You can purchase gun-locking devices which will render a gun inoperable when not in use. Make sure that you know how to disable the lock quickly, but know that using one can be a good idea if you have children or teenagers in the home. In order to avoid tragic accidents, it's important that you try to keep a cool head when you think there is an intruder in the home. Account for your spouse, partner, and/or other family members before shooting blindly. While the police should identify themselves if they enter your home, try to take a quick moment before shooting if someone breaks into your room. It could be an intruder, in which case it's important that you protect yourself, but you don't want to accidentally shoot a police officer.
A: Learn about the law in your state. Shoot if you believe you or a family member are in danger. Learn if you're required to try to escape. Learn if your state has a "Stand Your Ground" law. Learn if "Castle Doctrines" apply in your state. Keep your guns in a safe, secure place. Store your guns and ammunition separately. Consider using a gun lock. Identify that there is an intruder before shooting.

Q: MSM is found in protein sources including eggs, fish, poultry, and legumes. Most health organizations recommend eating 0.8 grams of protein per kilogram you weigh, or about a third as many grams as your weight in pounds. For example, if you weigh 140 pounds (64kg), your recommended protein intake is 53 grams per day. A 3 ounce (85g) serving of tuna, salmon, or trout counts as 21 grams of protein. A 3 ounce (85g) serving of poultry counts as 19 grams of protein, and 1 egg counts as 6 grams. The healthiest way to add extra protein to your diet is to eat more legumes, such as beans or peanuts. Additionally, go for lean cuts of fish and poultry instead of fattier red meats. While garlic and onion contain MSM and other sulfuric compounds, they're most often consumed cooked instead of raw. Since MSM breaks down during the cooking process, try adding raw onion and garlic to salads and dressings. Fruits and veggies are, in general, good sources of sulfuric compounds such as MSM. Leafy greens and cruciferous vegetables (such as cabbage) are especially good choices. Leafy green and other fruits and vegetables also contain vitamins and minerals that promote healthy hair, skin, and nails. Cooking breaks down MSM, so you don't get as much from cooked foods as raw foods. While cooked foods still provide MSM and other beneficial sulfuric compounds, try to eat MSM sources raw if there's no risk of foodborne illness. For example, snack on unsalted peanuts or have kale salads with chopped onions and grated garlic.
A:
Eat plenty of protein-rich foods. Go for garlic and onions. Add more Brussels sprouts, cabbage, and kale to your diet. Eat foods that contain MSM raw, if possible.
