When you first start playing the piano, understanding time signatures can be tough. Many beginners feel confused and don't know how to keep up. Here are some important time signatures that every newcomer should know about:

1. 4/4 Time: This is often called "common time." It has four beats in each measure. It's found in many songs, but it can be hard to move your hands along with the rhythm.

2. 3/4 Time: This is known as "waltz time." It has three beats in each measure. It can be tricky for beginners because the first beat is the strongest, which might make the rhythm feel uneven.

3. 2/4 Time: This time signature has two beats per measure and is often used in marches. Some beginners have trouble with the quick stops and fast changes.

4. 6/8 Time: With six beats in a measure, this one can feel fast and complicated, which can make it scary for new players.

To make these challenges easier, here are some tips to help you understand rhythm better:

• Practice Regularly: Try clapping or stepping to rhythms every day. This will help you get a better feel for the beats.
• Use a Metronome: This handy tool keeps a steady beat and makes it easier to learn time signatures.
• Start with Simple Songs: Find easy songs that use these time signatures so you don’t get too confused.

Even though learning rhythm can be hard, practicing in a structured way will help you improve over time.
