How to Make Music in GarageBand for Mac: Beginner Guide

GarageBand is free for all Mac users and comes stocked with 15GB of bundled sounds, 48 effects, and support for up to 255 audio tracks, according to a PCMag UK review updated earlier this year. For this workflow, there's no need to buy additional plug-ins or sound packs. This GarageBand for Mac beginner tutorial walks through how to make music in GarageBand for Mac starting from a blank project, built from Apple Loops, Drummer Loops, and optional recorded audio.

No MIDI keyboard, microphone, or audio interface is required for the workflow covered here. The loop-based path runs entirely on Apple Loops, Drummer Loops, and the Mac's built-in microphone and output, which Apple's own troubleshooting documentation uses as a baseline setup when confirming GarageBand is working normally (Apple Support). External gear becomes necessary for specific jobs instead, like recording vocals or guitar through a microphone or audio interface, or playing a software instrument live on a connected MIDI keyboard (PCMag UK). Readers who already own one of those get a faster, more expressive path, covered further down, but neither is required to finish the project this guide describes.

This is written for Mac owners with no prior production experience who want a finished, playable song by the end, not a tour of every GarageBand feature. The project stays small on purpose: one Drummer Loop beat, one melodic or chord part built from Apple Loops, an optional recorded vocal or instrument, basic volume balancing, and an export. That's GarageBand Mac music production for beginners: enough structure to turn a handful of loops into something that sounds like an actual song, rather than a pile of sounds left running on top of each other.

Set up your project before adding a single sound

GarageBand is described as a "powerful, beginner-friendly" free DAW (PCMag UK), and getting a blank project ready takes only a couple of minutes.

1. Open GarageBand and choose File > New. The New Project window asks for either a genre template or an empty project to build from scratch (PCMag UK).
2. Select Empty Project instead of a template. Starting empty keeps control over which instruments get added and when, and it's also the starting point Apple's troubleshooting documentation uses when checking whether a problem lives in a specific project or in the app itself (Apple Support).
3. Set a tempo before adding anything else. Something around 110-120 BPM is a reasonable starting point for a first project. If the song has an obvious key center, decide that now too, so chord and melody choices stay consistent as the project grows.

Decide now whether the melodic part will come from an Apple Loop, a connected MIDI keyboard, or a recorded microphone and guitar. Each path gets its own walkthrough below, and the choice determines what, if anything, needs connecting before moving on.

How to make music in GarageBand for Mac: build your beat with Drummer Loops

Drummer Loops are a customizable type of Apple Loop that generate a full, editable drum track in one drag, instead of requiring note-by-note programming (Apple Support, last year).

1. Click the Loop Browser button in the upper-right corner of the GarageBand window.
2. Select "Drummer" from the Sound Packs pop-up menu to filter the list down to Drummer Loops, which appear with a yellow icon.
3. Click a loop to preview it before placing anything; the preview has its own volume slider at the bottom of the browser.
4. Drag the chosen loop into an empty part of the Tracks area. GarageBand automatically builds a new Drummer track with a matching region, which can then be refined for feel and complexity in the Drummer Editor (Apple Support).

Drummer Loops come in three broad types, Acoustic, Electronic, and Percussionist, and mixing types on the same track matters: combining loops from different types can make the pattern sound different from what played in the preview (Apple Support). Settle on a short, repeatable block now. An 8-bar loop works well for this example, since it becomes the building unit for the full song structure later. A single project supports up to six Drummer tracks total (Apple Support).

Add a melody or chords: how to use GarageBand on Mac with a MIDI keyboard, or no hardware at all

With a beat in place, the project needs one more part: a melody or a simple chord progression. How it gets added depends on what's plugged into the Mac, if anything.

No extra hardware. Add a melodic or chord-based Apple Loop the same way the drum loop got added. Open the Loop Browser again, this time browsing by instrument category instead of filtering to "Drummer," and preview a few options until one fits the beat's tempo and feel. Drag the loop into an empty part of the Tracks area to add it to the project. GarageBand ships with thousands of Apple Loops spanning multiple genres, so a usable chord or melody line is normally a few previews away rather than something that has to be played or programmed by hand (PCMag UK).

MIDI keyboard. A USB-compatible MIDI keyboard lets a player record a part live instead of relying only on pre-built loops (PCMag UK). Setting up a MIDI keyboard in GarageBand Mac projects starts outside the app, in Audio MIDI Setup:

1. Open Audio MIDI Setup, located in the Utilities folder inside Applications.
2. Choose Window > Show MIDI Studio. Connected devices appear as icons; devices that aren't currently connected show up dimmed (Apple Support, earlier this year).
3. Select the device and click Test MIDI Setup, then play a note on the keyboard. The up arrow for the matching MIDI port should highlight, confirming the Mac is receiving signal (Apple Support).

If something doesn't work, where the problem shows up points to the fix:

• Device never appears in MIDI Studio. Check the USB connection and that the keyboard is powered on, then confirm it's compatible with the installed version of macOS and look for a manufacturer driver update (Apple Support).
• Device appears and the test lights up the port's arrow, but GarageBand stays silent. Confirm a Software Instrument track is selected and armed in GarageBand, and that it's actually receiving input from the keyboard rather than sitting unselected.
• A connected sound module or external instrument makes no sound. Check that cables run from the MIDI interface's out port to the module's in port, and that the module's own audio output reaches a mixer, amp, or headphones (Apple Support).

Microphone or guitar. Recording an electric guitar, bass, or a standalone microphone needs an audio interface, such as a Focusrite Scarlett 2i2 or a MOTU M2 (PCMag UK). A USB-powered microphone is the one exception, plugging straight into the Mac without a separate interface. Either a USB-powered microphone or an audio interface with a mic preamp supports recording at 24-bit resolution (PCMag UK). Create or select the track that matches the input, then arm it and click Record.

If hardware doesn't register on any of these paths, switch temporarily to Built-in Microphone and Built-in Output under GarageBand > Preferences > Audio/MIDI, then open a project that's been giving trouble. If playback works properly through the Mac's internal audio, the external interface itself may need an update or service from its manufacturer (Apple Support).

Turn loops into a complete song structure

A beat plus one melodic part is still just two sounds looping, not a song. Structure is what separates the two, and GarageBand builds it mostly through duplication rather than new material.

Use the 8-bar block as the base unit and duplicate it across four named sections: intro, verse, chorus, and outro. A workable starting recipe looks like this:

• Intro (4-8 bars): drums only, nothing else playing yet.
• Verse: bring in the melodic or chord part alongside the drums.
• Chorus: add the recorded vocal or instrument, if one exists, so the fullest arrangement lands here.
• Outro: thin things back out, drums alone or drums plus one part, rather than cutting off abruptly.

Duplicate regions in the Tracks area to repeat each section. Drag the copy directly against the end of the previous region rather than dropping it loosely nearby; a gap of even a fraction of a bar leaves an audible silence that's easy to miss until playback. Mute or delete individual tracks within a section to create contrast between verse and chorus instead of leaving every part playing start to finish.

Once sections exist, select a track and open its Smart Controls to balance levels. This surfaces the knobs, sliders, and buttons most relevant to that instrument, and adjustments made during playback can be recorded directly as automation (PCMag UK). Before moving on, confirm no single track is burying the others and that verse and chorus sound noticeably different by ear, not just on the timeline.

Save, export, and what to check if something's off

Finishing a first song doesn't call for full mastering, just enough balancing that the file sounds intentional. GarageBand's built-in mastering track raises overall levels for a more finished sound before export (PCMag UK); a light touch is plenty for a first project, and deeper mastering decisions can wait for later songs.

1. Save the project once the balance sounds right, then open GarageBand's Share menu and export the song to disk.
2. Choose a format: AAC or MP3 for sharing informally, AIFF or WAV, including 24-bit lossless WAV, if the file is headed into another DAW for further work (PCMag UK).

Before exporting, confirm the song has a clear ending rather than an abrupt stop, that sections sound different from one another, and that no track dominates the mix. Projects aren't locked to one device, either: a song started in GarageBand on iPhone or iPad can be opened later on the Mac through iCloud, useful for catching an idea away from a desk though not required for the workflow covered here (PCMag UK).

If a MIDI keyboard never responded during setup, rerun the Audio MIDI Setup test covered above. That test only confirms whether the Mac is receiving MIDI input; if it passes and the keyboard still doesn't play back correctly inside a project, the next thing to check is the project's track setup, not the connection itself.

Once this basic loop-based workflow feels comfortable, third-party Audio Units plug-ins and the Logic Remote app for iPhone and iPad are reasonable next tools, letting a phone or tablet play any GarageBand instrument wirelessly and adjust Smart Controls from across the room (PCMag UK). Check that any added plug-in matches the installed macOS and GarageBand version before relying on it: Apple's troubleshooting documentation lists incompatible or damaged Audio Units plug-ins as a known source of instability (Apple Support).

Save the finished project, export a copy that matches the goal, informal sharing format for a quick send, lossless for further editing, and treat a MIDI keyboard or audio interface as something to add later, once a specific song calls for live playing or recorded vocals, not as something that has to be sorted out before the first one gets finished.
