Electric guitar
Plug in, turn it up, bend that note.
Connect your electric guitar through an audio interface, put on wired headphones and play through an amp with drive and pedals. Then train the moves that make lead guitar sing: bends that land in tune, steady vibrato and tab that shows every technique.

Your rig and your technique
An amp in your iPhone
Gain, bass, mid, treble, volume and a noise gate, with a drive stage and a speaker cabinet. Start from the Clean, Crunch or Lead preset and shape it from there.
Four pedals
Compressor, chorus, delay and reverb stompboxes in the chain, each with its own controls. The presets switch the right ones on for you.
Low-latency live input
Your guitar goes in and comes out in the same short audio cycle, so the sound keeps up with your fingers. The screen shows the input level and the estimated delay.
Made for headphones
The amp plays through wired or USB headphones only: the speaker would howl and Bluetooth is too slow to play through. Unplug them and the amp switches itself off.
Bends & vibrato trainer
Choose a half, full or one-and-a-half step bend, or vibrato, on strings 1 to 3. A live graph shows your pitch in cents, and every attempt gets stars and a tip such as “bend 20 cents further”.
Tab with every technique
Bends and release bends, vibrato, hammer-ons, pull-offs, slides, palm mutes and harmonics are marked on the tab, and Listen plays them back so you hear how they should sound.
From plugging in to playing lead
Plug in
Connect your guitar through a USB or Lightning audio interface and plug in wired headphones.
Dial in your tone
Pick Clean, Crunch or Lead, set the input so the meter stays out of the red, then shape the knobs and pedals.
Train your lead moves
Bend into the target band in the trainer, then play the Lead Guitar Moves exercise with bends, slides and vibrato.

Questions
What do I need to play through the amp?
An electric guitar, an audio interface that connects to your iPhone over USB or Lightning, and wired or USB headphones. Set the interface's input level so the meter in Melody+ stays out of the red.
Why can't I use the speaker or Bluetooth headphones?
With a guitar plugged in, the iPhone speaker would feed back into the pickups and howl, and Bluetooth adds too much delay to play through. Melody+ only turns the amp on with wired or USB headphones, and turns it off if you unplug them.
How does the trainer know how far I bend?
It follows the pitch of your note through the microphone about 90 times a second and compares it with the target in cents. A bend counts when it reaches the target band quickly and holds there; vibrato is measured by how fast and how wide it is.
Can I practise bends on an acoustic guitar?
Yes. The Bends & vibrato trainer listens through the microphone, so it works with an acoustic guitar, or with an electric guitar played through an amp the iPhone can hear.
