If you want to improve your tajweed, starting with Noorani Qaida with Tajweed is a great choice. This book teaches the basics of Arabic pronunciation, helping you recognize letters, vowels, and rules for correct recitation. By practicing regularly, you'll develop a strong foundation in pronouncing letters from their proper articulation points (makharij) and applying essential rules like elongation (madd) and stopping (waqf).
To get the most out of it, read slowly and focus on clarity rather than speed. Listening to qualified teachers or audio recordings can also help you hear proper pronunciation and rhythm. Try to recite aloud and correct any mistakes along the way. A consistent daily practice, even for a few minutes, will make a noticeable difference over time.
