Swami Dayanand Saraswati Commentary : The Ayurveda – the science of medicine, the Dhanurveda —the science of arms and weapons = the military science, and the science of governance = state duties, the Gandharva Veda, the science of Music, and the Arthveda, - the science of architecture and technology, these four are called ‘Upveda’.

Comment in English : Note — The Ayurveda is from Rigveda, the Dhanurveda is from Yajurveda, the Gandharvaveda is from Saamaveda, and the Arthaveda is from Atharvaveda.
