To get better at music, train your ear a little every day, play or sing along with songs you love a few times a week, and get feedback on your own mixes once a week. Aden's free tools on tools.aden.space cover each of those steps: an ear trainer, coaches for piano, singing and guitar, Track feedback and a reference comparer. They run in your browser, need no account and are included in Aden.

This guide is the practice plan. For every tool in one list, read free music tools for producers and artists.

A weekly routine to get better

Tools help most when you use them a little, often. A plan that fits around a job or school:

1. Every day, 10 minutes: the Ear trainer. Stay on a level until it feels easy, then move up. Notes first, then intervals, then chords.
2. Three days a week, 20 minutes: play or sing a song you love. Use the Piano coach, Guitar coach or Singing coach. Start slow, then raise the speed a little each session.
3. Once a week: find the key and BPM of that song in the Key finder, then check it by ear. Your ear training starts to pay off here.
4. Once a week: run your latest mix through Track feedback. Fix the one note that matters most, not all of them.
5. Same day: compare it to a reference in Mix vs reference. Pick a released song in the same style and listen in blind mode.

Keep each week's mix, so you can hear how far you came in a month.

Train your ear

Ear trainer trains relative pitch, the skill behind playing by ear, transcribing a melody and hearing a key. You name notes on the piano, then intervals up to the octave, then chords up to sevenths, in any octave and on any sound. It keeps daily practice and stats, so you can see your progress. Guide: how to train your ear.

Practice piano, singing and guitar

Each coach listens, shows you where you are, and lets you go again at your own speed.

• Piano coach trains timing and hand position. Add any song as a recording or MIDI file and play it back at your speed. Notes fall onto the keys or onto your own keys through your camera, and every take is scored. Guide: how to learn piano songs online.
• Air piano teaches where the notes are before you own a keyboard. Your camera draws the keys on your desk, and tapping a finger down plays the key under it, harder for louder. Guide: how to learn piano songs online.
• Singing coach trains pitch. Sing any song or warm-up and see your pitch against the tune and moved to your range. Your camera can help with breath and posture on the high notes. Guide: how to sing in tune.
• Guitar coach trains reading tab and playing in time. Add any song as a recording or MIDI file and it becomes tab. Your guitar is heard through the microphone and every take is scored. Guide: how to learn guitar songs from tab.

Hear your own music clearly

These tools measure a track and say what they find, so you learn to hear it yourself.

• Track feedback trains your mixing ear. Drop or record a track, pick one genre or several, and read notes in words on the low end, balance, drums, sidechain, stereo, key and structure, with a mastering chain in order. Guide: how to get feedback on your mix.
• Mix vs reference trains you to judge a mix, not its volume. Your mix and a released song play at the same spot, loudness matched, and it shows where your lows, mids and highs differ. Blind mode keeps you honest. Guide: how to compare your mix to a reference track.
• Loudness check teaches how loud a master needs to be. It shows integrated LUFS, true peak and loudness range, and how much Spotify, Apple Music and YouTube turn it down or up. Guide: LUFS loudness targets for streaming.
• Key finder checks your ear. It reads the key and BPM of any song from its audio, its name or a link, on the Camelot wheel, and can listen live through a microphone or a browser tab. Guide: how to find the key of a song.
• BPM tapper sharpens your sense of pulse. Tap along and the click starts on your beat, so you hear at once whether the tempo is right. Guide: how to find the BPM of a song.
• BPM to ms teaches how delays and LFOs lock to the beat: every note value, straight, dotted and triplet, in milliseconds or Hz. Guide: BPM to ms delay times.

Write and record

• Note editor shows how one note changes a chord. Drop a sample and move its notes, or turn a minor chord into major in one press, then download the WAV or the notes as MIDI. Guide: how to change the notes in a sample.
• MIDI editor helps you try chord progressions fast. Draw notes on a piano roll or type chords, hear them on piano, guitar, synth or your own samples, and download the .mid. Guide: how to turn chords into MIDI.
• Vocal recorder gets you recording often. Drop a beat and record over it, or over a click, with vocal effects, and download a 24-bit WAV. Guide: how to record vocals online.
• Lyrics transcriber puts your words next to the music. Drop a song for its lyrics timed to the vocals, or time your own line by line, and download an LRC file. Guide: how to transcribe lyrics and make an LRC file.
• DAW project viewer lets you learn from other people's sessions. Open an FL Studio, Ableton Live, REAPER, DAWproject or Studio One file to see its tempo, key, plugins and samples, and play it without the DAW. Guide: open a DAW project without the DAW.

Make your own drum sounds

Shaping a drum yourself teaches you what pitch, decay and tone do. Export a WAV or drag it into your DAW.

• Kick generator: pitch, amp, click, drive and harmonics, or rebuild your own kick from a WAV. Guide: how to make a kick drum.
• Snare generator: the body, the wires and the room.
• Clap generator: the hands, the spread and the room.
• Hi-hat generator: closed, open or pedal.
• Crash generator: crash, ride, splash or china.
• Rumble generator: a kick into a dark, ducked tail, the techno low end.
• Drum kit: six drums and a groove that loop together, tuned to the kick in one click, exported as WAV or MIDI.

For everything but the kick, read how to make drum sounds.

Learn the release side

• Artist name check: whether a name is taken on Spotify, Apple Music and Deezer, in EU trademarks and as a social handle. Guide: how to check if an artist name is taken.
• ISRC lookup: the ISRC and UPC of a released song. Guide: how to find the ISRC of a song.
• Proof of creation: a certificate, signed by a qualified EU timestamp authority, that your file existed today. Guide: how to prove you made a song.
• Snippet video maker: a 10-second vertical video of your song for TikTok, Reels and Stories. Guide: how to make a music snippet video.

Keep your progress in Aden

The tools work without an account. Sign up when you want to keep your work. Many tools have a Save to Aden button that brings what you made over as a new track:

• Tracks with their details. The Key finder fills in the title, BPM and key. The BPM tapper starts a track at the tempo you tapped.
• Lyrics kept with the song. A song saved from the Lyrics transcriber keeps its lyrics, and you can sync them again after a change.
• Every version stamped. In Aden, every version you upload gets its own timestamp, with its credits and project.
• Recordings and projects. The Vocal recorder saves the beat and your take; the DAW project viewer saves the song with its bounce.

Create your Aden account to keep your tracks, their versions, lyrics and feedback in one place, so each week's mix sits next to the last.

Several tools also work inside ChatGPT and Claude, such as Key finder by Aden (mcp.aden.space/key-finder) and MIDI editor by Aden (mcp.aden.space/midi-editor).

FAQ

Are Aden's music tools really free?

Yes. Every tool is free and included in Aden. Two have a daily limit: the Lyrics transcriber runs up to five times a day, and Proof of creation stamps up to ten files a day and five an hour. Snippet videos carry a small aden.space mark at their foot.

Do I need an account?

No. Every tool works without one. You only sign up to save a track to Aden.

How long should I practice each day?

Short and often beats long and rare. Ten minutes of ear training a day, plus 20 minutes with a song on the days you can, is a good start.

Do my files get uploaded?

Most tools read your file in your browser, and it never leaves your device unless you save it to Aden. That covers Track feedback, the Loudness check, Mix vs reference, the Vocal recorder, the DAW project viewer, the Snippet video maker, the Note editor and the Key finder. A few work differently:

• Lyrics transcriber: the song is sent to transcribe the lyrics and deleted within a day. Nothing is kept unless you save the song to Aden.
• Proof of creation: only the file's fingerprint, with its name and size, is sent to be stamped. The file stays on your device.
• Key finder by name or link: it reads half a minute of the song's preview and keeps nothing of it.
• ISRC lookup and Artist name check: they search by the name or link you type, so no file is involved.

What languages are the tools in?

The analyze, create and release tools have a page in each of Aden's 17 languages, such as tools.aden.space/nl/key. The drum and practice tools are in English.

What do I need to use the practice tools?

A browser. The Singing coach and Guitar coach listen through your microphone. The Piano coach works with a MIDI keyboard and can use your camera. The Air piano uses your camera to see your desk, or you tap the keys on screen.
