When you're listening to a song, you may start tapping your foot or nodding your head to the beat. This beat is referred to as the pulse, what you count to when playing the song. Start by just finding this beat and tapping along with it. Often, the even beats are given an extra thump or sound, particularly in rock or pop music. So for instance, you may be hearing "thump, thump, thump, thump" as the beat, but then on top of that, you hear an extra bit on some beats, such as "pa-thump, thump, pa-thump, thump. Many times, the first beat in the measure will be given a stronger emphasis, so try to listen for that, as well. Even though the drums will often hit the even beats, other instruments in the song may hit the backbeats or the odd beats. So while you may hear a more solid thudding on the even beats, listen for the other beats to have emphasis elsewhere. For instance, you may hear chord changes on the first beat of most measures. Alternatively, you may hear other changes, like melody movement or harmony changes. Often, the first note of the measure is where major changes in the song happen. It can help to listen for strong and weak notes. For instance, the beats for duple time (2/4 and 6/8), are strong-weak. The beats for triple time (3/4 and 9/8), are strong-weak-weak, while for quadruple time (4/4 or 'C' for common time and 12/8), they're strong-weak-medium-weak. For instance, you may notice beats are grouped in 2s, 3s, or 4s. Count the beats out if you can. Listen for the first beat in each measure, then count out the notes, 1-2-3-4, 1-2-3, etc., until you hear the first beat of the next measure. If you are hearing 4 strong beats in a measure, you likely have a 4/4 time signature as that's the most common in pop, rock, and other popular music. Remember, the bottom "4" tells you the quarter note gets the beat, and the top "4" tells you that you have 4 beats in each measure. If you feel 2 strong beats but also hear notes in triples behind it, you might have a 6/8 time, which is counted in 2s but each one of those beats can be divided into 3 eighth notes.  2/4 time is most often used in polkas and marches. You may hear "om-pa-pa, om-pa-pa" in this type of song, where the "om" is a quarter note on the first beat and the "pa-pa" is 2 eighth notes on the second beat. Another possibility is 3/4, which is often used in waltzes and minuets. Here, you'll hear 3 beats in the measure, but you won't hear the triplets you do in 6/8 (a triplet is 3 eighth notes).

One-sentence summary -- Start by finding the main pulse or beat. See if you can hear an emphasis on certain beats from the percussion. Listen for the backbeats to have an emphasis from other instruments. Check for major changes on the first beat of the measure. Try to hear how the beats are grouped based on the cues. Choose the most likely time signature for the song.

Article: It might be a date if they show up in a dress, heels, or slacks, or it just appears in general that they put in an extra effort to see you. If your “date” is wearing an unwashed sweatshirt and it looks (or smells) like they didn’t even bother to shower, then it is probably not a date. If they ask you questions about yourself, pay attention to you, look at you often, listen to you, and generally seem like they care about you, then it is likely to be a date. It might not be a date if they are barely paying attention to you and are not trying to make conversation. If it was a date, you would be their current love life, not whatever they are talking about. It is not a date if they are going on about another person they are interested in, asking for relationship advice, or hitting on other people during the date. You can tell a lot about a situation based on someone’s body language. If they lean toward you, put their arm around you, try to hold your hand, or turn their body toward you, they might be interested in you. Whereas, if they are leaned over in the opposite direction, barely even noticing you’re on the other side of the couch, then it is not a date.  If they seem a little too comfortable and relaxed, you might be hanging out as just friends.  If they are nervous or fidgety it might be because it is a date. If they offer to pay for you, it is likely a date. If you offer to pay and they decline, pay attention to how they decline. If they seem weirded out you offered to pay at all, then it might not be a date. If they seem flattered but insist on paying for themselves, it might be a date. If they kiss you goodbye, then you can probably assume it was a date. Giving you a hive-five or handshake or simply just saying goodbye are not signals you just went on a date. It might not have been a date if they seem really offhand and casual about the goodbye (“See you later. Bye”). If they say a thoughtful goodbye, it is more likely it was a date. (“I had a great time tonight. I hope I see you again soon.”)
