Junior defence minister Peter Luff told the House of Commons about the missing items when answering a question asked by another MP, Luciana Berger.
Berger said that she thinks news of the thefts is "nothing short of a national disgrace".
Items to the value of approximately £700,000 ($1,121,000) have disappeared from the MoD's UK properties since May. In addition to the clarinet, the list also includes guns, several pairs of night vision goggles, ceremonial swords, a boat rudder, a helicopter rotor tuner valued at £50,000 ($80,097) and an unspecified amount of cash.
BBC News quotes Luff as saying that officers from the Ministry of Defence Police (MDP) are already working to reduce crime at MoD locations across the UK.
He said: "These officers provide an effective deterrent to potential criminals, by raising the awareness of staff, service personnel, service families and contractors."
