As a beginner in music theory, there are several concepts that you should aim to learn. Here are a few:

1. Pitch and melody: Pitch is the highness or lowness of a sound. Melody is the arrangement of pitches in a series that create a musical phrase or line.

2. Rhythm: Rhythm is the organization of sound and silence in time. It includes elements such as tempo, meter, and duration.

3. Harmony: Harmony is the use of two or more notes played simultaneously to create chords and chord progressions.

4. Scales: Scales are a series of pitches arranged in a specific order, usually starting and ending on the same note. They are the building blocks of melody and harmony.

5. Key signatures: Key signatures indicate which pitches are used in a piece of music, and they help to establish the tonality of the music.

6. Musical notation: Musical notation is the system used to write down and read music. It includes symbols for pitch, rhythm, dynamics, and other musical elements.

These are just a few of the basic concepts in music theory that you should aim to learn as a beginner. As you progress, you can explore more advanced topics such as chord progressions, modes, and counterpoint.
