NoteBuddies makes music theory stick. Whether you're a beginner learning to read notes or a student preparing for an exam, NoteBuddies turns music fundamentals into quick, focused practice sessions you can fit into any day. RHYTHM Drill whole notes, half notes, quarter notes, dotted rhythms, rests, ties, and triplets. Flip each card to reveal the beat value and name, or start a timed quiz to work through the full deck until every card is answered correctly. NOTES Read treble and bass clef notes on a real staff. Filter to treble, bass, or both clefs. Tap the card to reveal the note name, then test yourself against the clock in quiz mode. MUSIC TERMS From forte to fermata, master the Italian terms and symbols every musician needs to know. Filter by dynamics, tempo, articulation, or notation, then quiz yourself until the whole category is locked in. QUIZ MODE Every section has a built-in quiz. Cards you answer correctly are retired; cards you miss go back to the end of the queue. A live timer keeps you honest. Finish the deck and see your final time.
