As with all WP7 handsets, the Mozart packs a large capacitive touchscreen at 3.7 inches. However, it's still a fair bit smaller than the HTC HD7, which sports a 4.3-inch screen.
There's also a 1GHz processor, 802.11n wi-fi, Bluetooth 2.1 and GPS - plus compass, proximity sensor, accelerometer and ambient light sensor.
As with all HTC's WP7 handsets, the Mozart comes loaded with a bundle of apps - including weather, stocks and photo processing software - which can be accessed via a dedicated hub, pictured above.
All WP7 devices are required by Microsoft to sport three dedicated buttons on the front - back, home and search. The Mozart puts these buttons behind glass, making them virtual rather than physical keys - as shown above.
There's an eight-megapixel camera with Xenon flash, and the handset supports 720p HD video recording.
The left-hand side of the handset sports a volume rocker, and a MicroUSB port for charging.
The right-hand side has a dedicated camera button, shown above.
The top of the handset has the power button on the right, and a 3.5mm headphone jack.
Here's the back of the HTC 7 Mozart. The handset's chassis is made of a single piece of milled aluminium, with two rubberised patches - at the top and bottom - designed to improve grip.
The battery is removed by sliding off the rubberised plastic plate at the bottom of the phone and flipping a plastic bar down, as shown above.
Talktime on the Mozart is up to 330 minutes on WCDMA and up to 405 minutes on GSM, according to HTC.
